Check the DataBase for the HearMe Voice/Text Chat Hack. there are a couple of different versions that i have seen. I believe one of them forces the User to be Registered on your UBB to use the Chat application. It reads in your Member Cookie, and uses your UBB Member name for your Chat handle.
Also, the HearMe Software is Totaly ServerSide. It is embeded with a Small JavaScript. so its No strain on Your server, and its Fast loading and easy to use. theres not much of a Room Moderation system tho.
But, its worth a try if you REALLY want a Chat app on your BBS.
