Well, if you do meet, how do you know? Asking for a passport and driving
license? They can be more easily falsified than pgp signatures. In fact,
in Romania an entire industry is aimed at that.

The point is, if you don't know someone personally for a long time, identity
information can be falsified. If you want to sign someones key based on
paper ID's, I don't see why that would be more secure than looking up a
company name in the phonebook and call them.

If it comes at really important situations where my life might be at stake,
I don't see why I would trust anyone I have not met personally.
