Well, I understand you have needs, that's all fine and dandy; but keep in mind that the chat integrations at ubbdev are made by ubb members; I highly doubt that many chat companies want to maintain anything past an initial creation.
Still does not change the fact that Rick is one man working on one large product; people need to approach him when he has spare time to request he work with them to help get something working for THEIR product...
BTW, the reason other chat programs don't work in the manner you're wanting is because they work with existing items... For example, PJIRC is simply an IRC client that works on IRC Servers; your users COULD register their nicknames on the server of your choice...
FlashChat DOES integrate into the UBB, user database and all.
