The choice of XMPP server will require a reasonable amount of testing,
and may be influenced by your ability to use commercial software, GPL
software, etc. You can try out XMPP by creating a free account on
Jabber. Mostly acts like any old school chat program, a la AIM. Kind

in is the ability to know who is available at the moment. XMPP is not
very useful as a data exchange format, rather slow. HTTP being an
I believe Etoys has an XMPP class. No need to reinvent the wheel. The
best man to speak to that is Bert Freudenberg, the squeaker behind the
