My point was that AIM has full support for chat in the client, and with no server-side programming at all you can advertise chats on your site by simply posting an url in the following format:
aim:GoChat?RoomName=<YourRoomName>
When someone clicks on this url, the AIM client will open with the room name specified
Of course you'd want to point people to the aim download site so they can download the client and make an account if they don't have one already, the url is www.aol.com/aim
I didn't mean to trivialize your question, but I just wanted to point out that AIM could be viable for simple needs.
