As far as the classes involved in the implementation of video conferences are concerned, the ones I specified in my previous e-mail are a good starting point.
We demonstrated video conferences at FOSDEM 2012 so we've had them for roughly an year at the very least.
We're currently preparing a second type of video conference for a release which are aided by a server side technology that we call Jitsi VideoBridge.
The latest and greatest of these should be available to test in our nightly builds.
If you are experiencing particular issues with the support for video conferences in Jitsi please be specific about them in your reports so that we can give you detailed answers, references, help.
