Secure Key exchange

	1) I've met him before. (I wouldn't, for example, sign Tim
Jennings' key after meeting him for the first time at a cypherpunks
meeting, since I'd have no other way of identifying him. You, on the
other hand, may be someone I've met before (do you think so?) so I
might...) I've interacted with him to a reasonable extend, both
socially and technically (including one interview with John Markoff.)
	2) He signs my paychecks -- which is "good enough", since the
checks clear :-)
