As you might have heard by now everywhere. Google in cooperation with Jabber.org released the library Jingle (specs) used by Google Talk. Libjingle extends the XMPP Jabber and make it possible to add multimedia functionalities. It also makes it possible for developpers to connect their client to the Google P2P Jabber framework. For now only the VoIP is possible with the lib but other video and multimedia extaensions are possible and expected.
