I've written about WebRTC screen sharing, but today I came across another WebRTC screen sharing solution leveraging Openfire and using WebSockets and JingleNodes (XMPP) plugins. If you're not familiar with Openfire, it's a real time collaboration (RTC) server licensed under the Open Source Apache License. It uses the only widely adopted open protocol for instant messaging, XMPP (also called Jabber).

Code as simple as this allows you to share any video device, whether it's your webcam or your screen:

navigator.webkitGetUserMedia( {video:{mandatory: {chromeMediaSource: 'screen'}}}, this.onUserMediaSuccess.bind(this), this.onUserMediaError.bind(this) );
Here's a screenshot of me sharing two screens between two Windows 8 computers. (click for larger view)


Here's a full screen view after double-clicking the thumbnail real-time view of the other PC's screen (click for larger view):


The demo leverages Openfire using the WebSockets and JingleNodes plugins, which uses a simple XMPP Jingle library.
