Heya,
It's not the same room, though. I logged in with AIM and with Trillian under two different screen names. Started the AIM room and then tried to join with Trillian. They both said "jetcareers" but I could not see myself. Though if I join the chat room under one name in AIM, then invite my Trillian screen name then I can join fine. Kinda weird.
Cheers
