I'm curious as to how to do this.
As I understand it, the Jabber server needs to have an IRC Transport installed to support IRC chat.
For instance, I'd like to chat on #django which is on the Freenode network (I'm a total noob in this arena, so if I sound like I'm talking about teh Intraw3bz, it's because I don't know much about this stuff). I found an open server that let me do this through my Jabber client (Psi). But when I look at the transports for my Jabber server on dreamhost, I don't see an IRC transport.
Does one need to be installed for the Dreamhost-ed Jabber server to work with IRC? Or am I not understanding how to use my Jabber client to connect to my Jabber server?
