Right, but it would of general interest for the whole community for 1) understanding if EXI works for our case 2) client server developers that could use it The only XMPP specific part I'd require is the creation of the initial dictionaries for the most used namespaces, since EXI would be useless without them. -- Fabio Forno, Ph.D. Bluendo srl http://www.bluendo.com jabber id: [EMAIL PROTECTED]

I wish you luck! Hopefully PJS gets further than xmpp.py's xmppd, or Pretzel.
