I've been curious as to whether anyone has developed and/or whether it is technically feasible to develop a cryptographically secure listserver.

User would submit their PGP public key to the listserver upon subscription, submitted messages would be encrypted with the listserver's public key,

Actualy to be secure the subscriber would need to use one of the remailers public key to encrypt their key prior to submission to the remailer. Of course this doesn't prevent a MIT attack and key substitution. Otherwise you'd be sending your key in the clear, generaly a bad thing. This touches on the main problem with distribution and use of PKE, in that no secure key management protocal suitable for internet sort of architectures has ever been developed that doesn't require some trusted 3rd party or an existing secure channel. ____________________________________________________________________ The seeker is a finder.
