I'm posting this here in case some of you haven't seen it yet. http://www.craphound.com/spamsolutions.txt
it captures many of the obstacles in the way of a good solution.
it's kind of neat perhaps it could be implemented as a web service
so that you could easily construct a response just by clicking on a form.
I'm sure Ken's idea would fail on the
( ) Susceptibility of protocols other than SMTP to attack
( ) Extreme stupidity on the part of people who do business with spammers
( ) Dishonesty on the part of spammers themselves
and probably a few others.

You know, we could kill spam tomorrow if we could just convince people to set up & use PGP, and then drop all non-PGP-encrypted stuff at the MX.
It's a "computational puzzle" that I don't believe would be onerous to list servers. It's free (or, can be free if you want it to be) but would be a PITA for spammers to implement on a scale of millions.
I'd ask John Sechrest to set up the MX at PEAK to reject all non-PGP mail coming to me tomorrow...
... IF I could only convince enough people out there to adopt this solution that already has RFCs in place.
