Dear Lazzy Web, Fingerprint Scanning?

Anybody know of some open source fingerprint scanning software for OS X? Bonus points if it has magic integration with stuffs like the keychain, auto log-in, screen saver disable, etc.

Failing available open source software, what about commercial software? I’m aware of software from upek that supports their Eikom as well as ancient software from Sony for their Puppy scanner. I’m looking for something that would support multiple scanners, ideally the U.are.U stuff. Though if anybody wanted to trade a pair of USB U.are.U scanners for an Eikom one, that would be great too ;)
