I recently install Bitlbee on the comm image so that people who want to chat on IRC don't need to have a separate client open to chat with those who are less enlightened. All you need to to do is connect to the Bitlee server, and register your other IM accounts (Oscar/Jabber/MSN) and then it populates the 'control channel' with your buddies. Then it's a simple process of typing <BuddyName>: <msg> to send them a msg, or /msging them to chat with them in a separate window/tab. A very cool thing to play with overall.
Peace and chow,
