See http://www.jabber.org/ for detailed information about what Jabber is about. The basic idea however is that Jabber is bridging software - a definition of a client that can talk ICQ, AOL Instant Messenger, IRC, MSN Messenger and other instant messaging protocols.
There are at least three attempts at a Tcl Jabber client:
