[JDEV] libjabber 'port' and licensing

[Dave]

I'd prefer to avoid HTTP polling if possible, due to the fact that there's
no secure Jabber over HTTP polling standard, ATM.  It's really a rather
ugly solution, anyway.

If they have a transparent proxy (i.e., forwarding all queries to remote
port 80s to the proxy, or forwarding all queries that look like HTTP
requests to the proxy) and it supports keepalive connections, you may
be in business anyway.  Either way, trying to telnet to a port 5222
somewhere and giving a non-HTTP-like initial data stream will reveal
whether or not general outgoing TCP connections are allowed.
