Use one PPC as AP for another

So...How can I use my Titan (Which has unlimited vision) as an access point for my Vouge? My titan is currently activated on the line while I am rebuilding the ROM and stuff, and I'd like to be able to get on the net with the vouge. The vouge doesn't have wi-fi, so that kinda puts it out of the picture.
Somehow there should be a way to share the internet connection (either wifi or evdo) over bluetooth from the titan to the vouge. I know internet sharing has BT PAN as an option, but I don't think it works phone 2 phone. Any ideas on how this could work?
