An IRC gateway for Jabber
http://www.jabberstudio.org/projects/ijchain/project/view.php
PT 14-Nov-2004: I have had so much trouble trying to get all the Perl modules required by this app installed and working on any of the systems available to me that I gave up and have written an IRC-Jabber bridge in Tcl instead. This takes the irc side of the tclapps ircbridge and adds Jabber client code to bridge the jabber chat conference with the #tcl irc channel.
DG is off building a better one (yes, it's written in Tcl): ijgate
It's far more entertaining to regard ijchain as another personality, coordinate with its peers as listed in "Tcl Chatroom".
