Who will be the first one to come out with an iPhone app that allows you to take a picture of someone and then automagically find the persons name using facial recognition?

It really seems like a pretty simple idea, especially with an API, which is already attached to Facebook, that does all of the work for you.

The API seems a bit limiting, though. For example, you must specify a list of possible users "you're looking for" in order it to find a match. The only way around this seems to be creating a private namespace that includes your own index of all Facebook users, etc.
