Google Talk now supports XMPP Jingle
http://juberti.blogspot.com/ 
"we've just finished updating Google Talk and its related services to speak 
XMPP's Jingle call signaling protocol."
...
The announcement:
"We are pleased to announce that we have launched support for Jingle
XEP-166 and XEP-167 for Google Talk calls to and from Gmail, iGoogle,
and Orkut. We have also added the same level of support to libjingle
(http://code.google.com/p/libjingle), which is used by many native
clients. From this point on, it will be our primary signalling
protocol, and the old protocol will only remain for backwards
compatibility."

Subject: Google opening up video groupchat specs (surprise, it's XMPP based!)

Is interoperability with Google's video groupchat on the horizon? Probably so 
(see article below)... they let it slip that it's XMPP/Jingle based, so it 
may actually be interoperable with things WE do.  This could fit into some of 
the work we've proposed/discussed, especially with the Internet2 Commons.   
Has anyone had any experience with Hangouts / have you attempted 
interoperability? (Does anyone know Justin Uberti? perhaps we can invite him 
to one of the calls.)

Google plans to open Hangouts for interoperability:
http://gigaom.com/video/google-plus-hangouts-interoperability/
"Hangouts, the group video chat component of Google Plus that everyone's been 
raving about, could eventually be usable with other video chat clients and 
services as well. Google Real-time Communications Tech Lead Justin Uberti 
wrote this weekend on his blog that the company plans to publish the 
specifications necessary to interoperate with Hangouts."
...
"At a high level, it's based on XMPP MUC (XEP-0045) and Jingle 
(XEP-0166/167), with some other enhancements needed to handle our 
architecture."
