Google, Jabber, and Jingle
An anonymous reader writes "Jabber has published the experimental draft Jingle specs, which extend XMPP for use in voice over IP (VoIP), video, and other peer-to-peer multimedia sessions.
Google released an open-source library called 'Libjingle' on SourceForge. Libjingle is a set of components provided by Google that let your programs interoperate with Google Talk's peer-to-peer and voice calling capabilities. The package includes source code for Google's implementation of Jingle and Jingle-Audio."
