[XCON] draft-boulton-xcon-session-chat

Hi Mary and Chris,

I have just have a quick look at this draft and I have to say that I 
like the idea to have
an xcon draft describing mechanisms and functionalities for a generic 
group chat conference
in a protocol agnostic way.
However the draft seems to me too tight to SIP / MSRP chat mechanisms 
that as far as I know
it is not yet be deployed anywhere, and instead does not say anything 
about other so to say
successful chat protocol like xmpp that is largely deployed and used 
within the Internet.

In order to have a more general description of the problem I think you 
should have a look at
- XEP-0045: Multi-User Chat http://xmpp.org/extensions/xep-0045.html the 
XMPP protocol extension for multi-user text chat
and to
- http://tools.ietf.org/id/draft-saintandre-sip-xmpp-groupchat-00.txt 
that is a first tentative of interworking between xmpp and mrsp-chat.

for example it should be interesting see and discuss in this draft how 
xmpp set a chatroom, a nickname etc. etc.
and describe how it could be possible do the same things using ccmp.

regards
Sal
