Collaborative Free P2P Screen-Sharing for Macs and PCs with ScreenHero

Robin Good's insight:

ScreenHero is a downloadable app for Windows and Mac computers that allows you to collaborate one-on-one on the same app with someone else at a distance.

ScreenHero has recently added full support for Windows PCs and it now integrates a voice feature allowing you also to talk with the person you are collaborating with.

Your login credentials and session data are fully encrypted using a P2P TLS scheme (SSL based).

ScreenHero operates as a P2P app, allowing parties to hook up directly to one another, and resorting to its centralized servers only when a direct connection is not possible for some reason.

My comment: An excellent screen-sharing tool for distributed teams. If you regularly operate with someone else at a distance and you need to easily and reliably share screens to see and edit drafts, mock-ups, presentations or code, ScreenHero is a great resource.

N.B.: If you are on a PC you will need a recent version of Windows, as PCs with Vista and earlier Windows versions are not supported.

Free version available.

P2P + WebRTC: Share Any File of Any Size with Anyone Instantly via Sharefest

P2P + WebRTC: Share Any File of Any Size with Anyone Instantly via Sharefest | Online Collaboration Tools |
Robin Good's insight:

With the introduction of the WebRTC protocol, any browser wanting to become a vehicle for P2P real-time communications, that requires no software downloads or central servers, can now do so.

"In real terms, WebRTC enables features such as videochat, VoIP calling, and peer-to-peer (P2P) file-sharing, all within the browser."

One of the first apps taking advantage of the new protocol is Sharefest, an open-source browser-based app which allows you to send any file of any size to anyone that has its reference link. Just like a P2P torrent file the more people downloading it the easier and faster the transfer will be.

Sharefest essentially let's other people securely connect directly to your computer via the WebRTC protocol and to initiate a mesh, distributed file download that draws on your original file as well as on the parts of it already downloaded by others.

It goes without saying that you need to keep your computer on for this file transfer to take place unattended. 

"Sharefest operates on a mesh network similar to BitTorrent and all transfers are executed peer-to-peer. Files can be shared with many people at once and the technology can swarm to speed up transfers, just like BitTorrent. It’s Open Source and apart from Chrome or Firefox, no additional software is required."


"Sure, you could use Dropbox, YouSendIt, or even BitTorrent sync to do the same thing, but with Sharefest there's no extra software to install; no account registration; there's no centrally located server on which file delivery depends. And once other users download the file, they can expand the network as well, providing additional peer-sharing power."


My comment: Excellent direct P2P file-sharing tool, has no limitations in terms of file size, speed or number of people that you can distribute it to. Super-easy to use, free and open-source. Hard to beat.

N.B.: Currently, it works only with files under 250 MB (MioBook reports)

Free to use. 

No downloads and no registration required.

Ciao Robin, piacere di conoscerti! Ho provato a trasferire un file piuttosto pesante (circa 7 Gb) e il programma Sharefest dichiara la restrizione di poter caricare solo fino a 250 MB (per adesso...). Si tratta comunque di un servizio ottimo... Grazie ancora per la notizia!
Robin Good's comment, August 18, 2013 7:12 AM
Excellent feedback! - I have contacted the developer via Twitter to get a confirmation on this, but your response is already very clear. Thank you MioBook for your useful contribution.

Technisch funktioniert der Dienst in der Tat: Ich habe eine Word-Datei via Sharefest geschicht und auch prima erhalten. Es stellt sich die Frage nach den richtigen Szenarien.

P2P Social File Sharing: Send Large Files To Any Fiend on Facebook with Pipe

From the official site: "As surprising as it sounds, there's currently no easy and effective way to transfer a file to a friend via Facebook. Pipe has taken a common feature of communication - attaching a file - and turned it into something simple and fun to use.

Privacy is guaranteed as it's a direct connection from one device to the other, between friends.

Pipe creates a direct, real-time connection between two devices with no intermediary server.

Pipe starts as an application on Facebook, and is then migrating to mobile devices and tablets.

  • Support for any file format, up to 1GB
  • Only the sender needs to be on Pipe
  • Invite a friend to Pipe with a simple file transfer
  • Direct connection with no intermediary server

A Decentralized Secure P2P File-Sharing, Chat and Discussion Network: RetroShare

A Decentralized Secure P2P File-Sharing, Chat and Discussion Network: RetroShare | Online Collaboration Tools |
Robin Good's insight:

RetroShare is a cross-platform, open-source, trusted and distributed P2P communication software and social sharing network.

Retroshare allows you to chat and share files of any size with your friends and family, using a web-of-trust to authenticate peers and OpenSSL to encrypt all communication.

RetroShare provides filesharing, chat, messages, forums and channels. Other key features include:

  • Serverless, completely decentralised
  • Multiple simultaneous downloads / uploads
  • Search Friends
  • Messages
  • Forums
  • Channels
  • Voice over IP
  • Instant messaging
  • Groupchat
  • GnuPG Authentication
  • OpenSSL Encryption
  • adding downloads via website links
  • Plugins support
  • UPnP / NAT-PMP port forwarding support
  • Graphical User Interface written with Qt4 toolkit
  • System tray integration

RetroShare has been inspired by the design of the Turtle algorithm:

"When designing Turtle, we were inspired by the way people living under oppressive regimes share information deemed "hostile" by their government (this can be books, newsletters, video and audio recordings, or even political jokes). Because of the potentially very serious consequences raising from being caught possessing/distributing such material, no single individual is willing to share it, except with close friends. Experience has repeatedly shown that, even in the most repressive environments, this "friends-to-friends" delivery network is remarkably effective in disseminating information, with relatively little risks for the participating parties; if one chooses his friends carefully, the chance of being caught doing the forbidden exchanges becomes very small."

Retroshare "... makes it difficult to intrude and hardly possible to monitor from an external point of view." This makes government monitoring and prosecution impossible beyond the will of Retroshare users

Free to use.

Personal P2P Mesh Network: Share Mobile Access From Your Smartphone To Any Computer

(Reuters) - "Travelling and looking for Internet access?

A new smartphone app allows users to share mobile Web access for free with other people nearby who have the same app.

Called Open Garden, the app forms a mesh network that enables each person connected to it to relay it to other users.

"Every smartphone is a computer and a router, so we thought it was the right time to interconnect all of these devices together to make general access more ubiquitous," said Micha Benoliel, co-founder and CEO of the San Francisco-based company Open Garden."


From Lifehacker: "Open Garden is both a Wi-Fi tethering app and a mesh network. Install it on your Android phone and you can use your mobile data wirelessly on your Windows or Mac laptop, as well as Android tablets.

Not only that—you can piggyback on others' mobile connections.

Once you've installed the app on your phone and the client on your computer, Open Garden will run in the background managing the connection over Bluetooth.

The Android app shows you all the devices connected in Open Garden, as well as the data being transferred.

Open Garden supposedly sniffs around for other devices using Open Garden and will manage the best way for yours to get online."


Available for Android, PC & Mac.
