Unfortunately, requiring that they have a published public-key *is* a burden to the average user. J. Random Luser just wants to sit down at his PC, boot up Winders, bring out Lookout, and forward a garish HTMLified email full of stale jokes to his buddies, complete with pictures, and he wants it to go through, without a hitch, right now. He thinks public keys are the ones hanging on the gas station wall, for the bathroom. He thinks crypto is someone from Superman's home planet. He thinks the IETF is them guys whut raided David Koresh. He has no clue what the ASRG is, but he thinks it sounds dirty. Make it worth their while, by coming up with infrastructure such that they won't get any spam if they have a public key, and MAYBE they'll bother doing it, IF the ISP will hold their hands every step of the way (and not charge them too much, including for issuing new keypairs when they let the private ones slip out too much). Of course, this means that all their equally technically-enlightened friends have to know how to USE his public key.... This sounds very much like the use of extra headerz, or a password on the subject line, but on steroids. In the end, possibly useful, IF you can get everybody aboard, but they won't go until everybody ELSE is already on board, and meanwhile it's a pain in the proverbial posterior to everyone who wants to communicate with the people using it. -- Dave Aronson, Senior Software Engineer, Secure Software Inc.
