I briefly thought about doing this a few years ago. Actually, I was even more interested in leveraging it for the key distribution and distributed identity management aspect. But then, when I looked at the various app interfaces and designs, I ran away from Facebook very quickly. It was absolutely impossible to do anything on Facebook that is secure in the face of other apps. Unless they've done a very un-Facebook-like revision, you cannot achieve meaningful security. Greg.
