*Discussion*

The group continued its discussion of the role of XMPP. Deke argued that to 
the
extent we can do PIC with XMPP and Jingle, we should do so, even if Google 
Talk
doesn't qualify as a reference implementation. Candace noted that the SIP.edu
group seems amenable to this approach. The fact that XMPP is being developed
outside IETF makes the process less transparent; on the other hand, XMPP isn't
concerned with integration with traditional telephony, which removes a lot of
baggage from the spec. Deke noted that there are cases where competing 
standards
exist side by side without interoperability, as with Windows Media and
Quicktime. Joe suggested that the different strengths of SIP and XMPP might 
lead
to a similar situation, with people using SIP for voice side by side with 
Jabber
for IM and presence, without interoperability.

Deke suggested that the group's next step should be to spend a couple of 
months
deploying Jabber services with Jingle extensions, and see where that takes us.
There was general agreement; there was also general agreement that no formal
announcements or changes to the group's charter are needed -- the group is
adding XMPP to its toolkit, not dumping SIP. Candace noted that the Jingle
drafts still say the spec is not yet ready for implementation. Ben T. 
suggested
reaching out to schools that participated in the I2IM group, as some of them
have experience deploying Jabber servers.

Rodger noted that the AJAX approach to web programming [See
http://en.wikipedia.org/wiki/AJAX] is very hot right now, especially in the
Jabber community. Windows Live Messenger is also built with AJAX.
