If you indeed have two picture id's that prove you are bill
gates, or john smith, or whoever, and the key ID matches the picture
ID, then yes, you would have my signature.
This is the weakness of the PKI -- and witha decent forgery,
you can indeed violate the web of trust. The point? We are willing to
accept the fact that there is a risk that a decent makeup artist +
forgerer could indeed penetrate security here.

How can you know someone's private key? (A nit: In any case,
you don't sign a private key -- you sign a public key).

I would not sign a key unless the ID field in the key matched
the physical ID that I saw. And you matched the pictures on the ID. I
assume that implicitly when I see a signature on a pgp key.
