The svc_irc module of the Jabber server listens on port 6667, and behaves as
if it were an IRC server.  It even supports a "NickServ" service for
authenticating with the Jabber server.

Jabber clients connect to the ICQ server via the "ICQ Transport," a slightly
different piece of server software, that acts as a bidirectional translator.
The ICQ protocol is actually fairly-well understood, and there are several
open-source ICQ clients; the ICQ Transport builds on that work to translate
outgoing Jabber messages into ICQ messages, and incoming ICQ messages into
Jabber messages.  In essence, the ICQ Transport is a big ICQ client with the
Jabber protocol as a UI.

You can follow ICQ transport development more closely by subscribing to the
icq-dev at jabber.org mailing list; check icq.jabber.org for details.
