*Discussion*

Rodger has found someone at Sprint who is interested in discussing IMS with
the PIC group. Rodger is also pursuing a contact at Verizon.

Most of the call was spent discussing and experimenting with Google's
"open federation" for XMPP (see
http://googleblog.blogspot.com/2006/01/open-federation-for-google-talk.html).
Ben T. is interested in seeing what kind of DoS attacks this will be subjected
to, given its openness. Rodger pointed out that calling this a federation is a
stretch, given its "implied trust of all comers", but agreed with the rest of
the group that it would be worthwhile for PIC to put some more time into
experimenting with it.
