It seems that the AOL protocol has undergone some changes since the original specification. The problem is that the information that is out there on the changes has come from reverse engineering/packet sniffing. There is, therefor, no license available so I cannot make the relatively trivial changes necessary.
We are still trying to contact AOL to get some official word from them, and as soon as we know more, we'll update everyone.
As to the Google Talk software, I agree, the open Jabber protocol would make for an excellent platform to build on
