*Discussion*

Michael Gettes joined the call to discuss possible areas of XMPP work. The 
group
reviewed the histories of the PIC and I2IM (Integrating Infrastructure and IM;
http://middleware.internet2.edu/i2im/) working groups. There was general
agreement that there is no particular synergy between I2IM's mission and 
PIC's,
though Michael and possibly other I2IM members are interested in working with
PIC on XMPP. The group reached a tentative consensus to move forward in the
following areas:
- rich presence, including "realtime telemetry" tied to the apps layer -- e.g.
the packet loss measurements that one of the MM demos used to advise users on
whether or not to bother trying to use video
- an XMPP "message bus"
- implementing both of these with non-proprietary software

The group agreed that the immediate next step should be to draft requirements
and scenarios. There was also general agreement that the 
requirements-gathering
focus needs to be complemented by "playing with cool new stuff", rather than
counterposed to it. The group will start with requirements and scenarios,
experiment with whatever XMPP tools are available, and use that experience to
suggest new possibilities, to be turned into further requirements and 
scenarios.

The group was also joined by Mark Sirota, a programmer at Penn who'll be 
helping
with the XMPP work. Mark noted that there are a few XMPP clients that can
integrate multiple forms of communication (IM, voice, video, whiteboarding, 
file
transfer...)  Among these, Psi (http://psi-im.org/) is particularly 
noteworthy,
as it's open-source and cross-platform, and has a large development community.
[ACTION] Mark will join the May 25 call to describe the XMPP environment 
that's
been set up at Penn.
