Pidgin 2.6 Adds Google Talk Video and Voice Support
August 19 2009, 10:44pm
"The big new feature in the 2.6 releases is video and voice chat support over XMPP, known primarily as the Jabber/Google Talk protocol. Unfortunately, that video and audio chat support isn't working on Windows at the moment (kind of a big target to miss, no?), but the Pidgin team says it's coming soon."
