What we need is a verification mechanism that is independent of the distribution mechanism.  When verification is independent of distribution it is readily apparent when the distribution mechanism has been compromised: verification fails.

I think you truncated my message before I actually describe something 
similar to this sort of service. Also, this is only one of my scenarios. 
There is another scenario where two entities wish to communicate 
privately. There needs to be a mechanism that allows people to exchange 
keys under separate cover secretly.

I toy with the idea of a P2P program that does encrypted exchange as an 
add on to services like skype or AIM
