Google stays on the XMPP train with Wave

‘Wave’ is an extension of XMPP.

The core of XMPP is ratified by the IETF and the XSF (XMPP Standards Foundation) manages the process of adding new functionality via XMPP Extension Protocols (XEPs)

Hopefully Google will get Wave into the XSF process as a XEP.
