That sucks... I was just about to ask if someone was working on a UBB integrated chat script.
Hey Mutt, you might try taking a gander at EveryChat anyway to see what you think of it.
I have a zipped file with all the good hacks for it I've found (there aren't many) included:
http://www.donmar.ca/everychat36.zip This script, even if it generates high server strain, would be useful for small groups of people (moderators for example) to collaborate in real-time, and would make a nice compliment to the online.cgi hack I like so much. A good enough CGI programmer like one of you guys could probably reduce the load it creates considerably, too, in addition to the UBB intergration. Just a thought!
