News.Com: IM compatibility closer to reality. Called the Extensible Messaging and Presence Protocol, the group's instant messaging standard gives Internet users hope of one day being able to send messages to anyone on the Net, no matter what software they are using. [Tomalak's Realm]

Ok, this is what happens every day on my desktop:

• Proteus, a very good multi-protocol IM client, handles my ICQ, MSN and Jabber accounts (ICQ is our company standard)
• Yahoo! Messenger handles my yahoo! account since a few weeks ago something was broken on their servers' side and Proteus crashes if I receive a message from a Yahoo! user.
• I use iChat both with my AIM/.Mac accounts and with Rendezvous, mostly because it's very cool and allows me to easily send files around my LAN.
• Radio is always logged on a Jabber account to manage outlines update notifications.

Now, if somebody could help sorting this whole thing out, it would really be welcomed.
