Zero Knowledge Trust? (was Re: Very funny, Polyanna :-( [namespace pollution])

However, all of these require some out-of-band communication to make sure you have the real key. Unfortunately, *every* Privacy Enhanced Mail system has this *feature* (or mis-feature, or bug, or however you feel like looking at it).

I feel like looking at it as a necessity. Every system for dissemination of public keys requires at least two paths of communication. If there is only one, an interposer can sever the connection graph of key assurances and create two different key worlds. Eric
