Karl's idea about message havens is interesting, but I don't fully follow how it differs from the anonymous pools we discussed last year (one such pool is being run from the extropia site, I believe). With a message pool the receivers sift through all of the messages to see which they can decrypt with their own public key. Messages can be sent to the pool via anonymous remailers. One problem is that there may not be too many subscribers to any one pool, so there is not much protection to the users. With a protocol more similar to WWW or gopher you might have a larger population of users, although again you don't have any guarantee of how many other people are downloading all of the messages. The other variant on this idea we have discussed is to use Usenet, as we have seen when people post encrypted messages to Pr0duct Cypher on alt.security.pgp. This seems to me to be an inefficient way to send mail (sending it to thousands of sites just to get to one person) but it certainly seems to provide good cover to the receiver. He could be literally any of probably tens of thousands of readers of that newsgroup. Hal
