IETF Extensible Messaging and Presence Protocol (xmpp)

Does anyone have insight (direction, momentum, chance of success, etc.)
into this IETF Working Group [1] which provides a generalized,
extensible framework for exchanging XML data? Their Core draft [2]
specifies "a protocol for streaming Extensible Markup Language (XML)
elements in order to exchange structured information in close to real
time between any two network endpoints.". 

Thanks,
Joe
