Well, this could be useful for voice verification of fingerprints. One
could then match the user on the phone to the key or something like that.
;-) I don't know how much it would be worth though.

There's no reason you couldn't select a key by a photo id in a GUI
environment. Simply show a bunch of photos and let the user choose.

Personally, I'd really like to see a keyserver interface that shows things
like this. I think that would be a great application of photo IDs.

BTW David, did you happen to have any thoughts on the handling of photo IDs
with revoked self-signatures, etc. as I talked about in a message a few
days ago? The same issues would likely apply to the other types of
non-traditional uids.
