*Discussion*

The group discussed use cases to guide its XMPP work. Rodger suggested using
presence capabilities in situations in which you need to find who's available
to deal with a location-specific problem. For example, at universities,
security personnel need to dispatch people to check that doors are locked
or unlocked; at factories, when a problem arises on the assembly line,
managers need to quickly find the closest person with the skills needed to
fix it.

The group revisited two use cases from its earlier work. Deke likes using
integrated communications to "deal with a common failure mode", like the
"network too busy for voice, try IM" notification at one of the Member
Meeting demos. Rodger noted that students can use presence technologies
to form ad-hoc study groups -- "who else is in the library right now?"

Rodger also suggested an absence use case: putting motion detectors in
meeting rooms so people can know when no one is there and the room is
available. Ben T. noted that there's been some interest in SIMPLE-based 
presence
for medical telemetry; Rodger noted interest in a "medical user agent" that
would manage the sharing of medical records on a token. Deke suggested using 
GPS
to track when enough people had assembled for an event to begin. Rodger noted
that some web conferencing software has such "critical mass detectors", and
suggested that similar technology could be used to track campus tours, so 
that,
e.g. the person designated to show off the library knows when the tour group 
is
about to arrive.

Steve is no longer able to work on the XMPP strawman document; the group
discussed how to proceed. Deke suggested we work on the doc on the conference
calls, using an XMPP chatroom 
()
 to augment the voice
discussion and submit proposed text. There was general agreement with Deke's
suggestion; send email to Mark Sirota 
()
 for an account
on the XMPP server. Deke also suggested a starting point for the document:
getting a server running, doing basic cross-platform communications with at
least two forms of communication (IM and voice), and then adding presence.
