wrong.  islands of trust already exist, it's a matter of 
building bridges between them.  

my site knows me well.  Your site knows you.

Therefore your site can certify (sign) your public key.  Mine can
certify mine.  All that is required now is for our sites to cross 
certify each other's keys.  

Or we could set up a CA hierarchy. There's nothing new here. Look 
at X.509.  

Oh, I almost forgot.  I haven't said DES, RSA, or public-key
encryption yet.  I'll say it now. RSA. Funny, but the solution
still works.  

(btw, what *is* unsolveable is a secure exchange of pks on a single 
insecure channel, not the prop. of trust.  Of course, pks can be exchanged
securely using a secure channel, such as a face-to-face meeting
where we show passports, or some other acceptable id.).
