One company I know of (www.tapeware.com) offers tech support
on ICQ.  Older ICQ clients (pre ICQ2000) could quite happily
communicate (messaging only) using UDPRELAY with only udp port
4000 opened.

I haven't tried ICQ2000a behind our firewall here (as we have
no requirement for ICQ as part of our business) to verify if
the same thing is possible with ICQ2000a.
