Not a big fan of them myself, have done it one or twice on MSN. Did a bit of it back in the BBS days, before the Internet, whilst at College. Maybe I've outgrown it!
However, I am interested on how you plan to incorporate it with Aquatic Babble. I haven't come across reference to an integrated Chat feature (yet). Wouldn't you need a Third Party Host? Is there a co$t?
