*Discussion*

The call proceeded in parallel with a discussion in the Internet2 PIC chatroom
().
 Chatroom participants used a variety of OSes
(Windows, Linux, Mac), clients (Gaim, Adium, iChat, gmail), and servers
(gmail.com, jabber.org, jabberwocky, another server at Penn); Deke observed 
that
the discussion provided "an existence proof of multi platform, multi client,
multi server IM." Material from the chatroom is being incorporated into the
minutes of this and future PIC calls. Neal noted that email is becoming less
practical due to spam; at the same time, IM is gaining, as it's harder to 
spoof
a sending address with IM than with email.

Neal has been looking into firewall and NAT problems with IM, and doesn't see
any of the proposed solutions bearing fruit soon. For  information see:

[ACTION] (6/15) Mark will add Libjingle to his list of things to check for
server/client support.

The group discussed the concept of "the electronic peanut gallery" -- buddy
lists being automatically created based on the presence of individuals at an
event, then turned into a chatroom for use during that event. Rodger noted 
that
Peter St. Andre implemented this with Bonjour; Neal pointed the group to
http://www.jabber.org/jeps/jep-0174.html. [ACTION] (6/15) Neal will look for
other standards that could be used to implement the "electronic peanut 
gallery".

The group discussed approaches to XMPP encryption. The basic division is 
between
the IETF S/MIME-over-Jabber approach, which appears to have little support
within the Jabber community, and the approach described in
http://www.jabber.org/jeps/jep-0116.html. Neal also pointed the group to a
related entry on Peter St. Andre's blog:
