I just woke up a little whlie ago, and am about to jump in the wet room. I have been screwing around with the Jabber Instant Messaging system this morning. It seems kinda neat, since it not only supports their own open-standard, open-source, XML based messaging protocol, but when you connect to one of their servers, it also acts like a ‘proxy’ to AIM, ICQ, MSN Messenger, Yahoo! Messenger, etc. So you can have one unified client to communicate on many different networks.
