Chrome version 26 stable and Firefox (Nightly build) now support full desktop screen sharing. In Chrome, you have to enable "Enable screen capture support in getUserMedia()" with the chrome://flags URL.

Clik here to view.
As the desktop screen is treated as a video device, you only have to make a change to the getUserMedia method for video and your existing application will work with no further changes. As an example, I only made the following change to my webrtc video example and now it allows two users to share their desktop screens
navigator.webkitGetUserMedia( {video:{mandatory: {chromeMediaSource: 'screen'}}}, this.onUserMediaSuccess.bind(this), this.onUserMediaError.bind(this)
);
To see it in action, just click on this URL https://webrtc.free-solutions.org:8443/webrtc/screen.html from two different PCs. Register with two different user names (no spaces or special characters).
