Let me explain. You can push on a standard, but that doesn't change any code. If everybody in the world read mail with /bin/mail, then you could rewrite that and add encryption. What certainly is the case, though, is that there are a lot of mail readers out there. It is also the case that the cypherpunks, of all people, should be using encrypted mailers. Otherwise we are hypocrites. Fen advocates MIME, and Ittai concurs. Ittai asks, relating to existing MIME development work:
Do we really want to give them an additional burden -- or do we want to leverage off work that is already being done?
It was my vision of this development that people here on the list would do the work of integration and publish the results. It is also my suspicion that simple PGP decryption support is fairly straightforward, being mostly the ability to run a command on a block and replace the block with the output of the pipe. This model works with regular mail and MIME, since it runs at the very top level of the application. Eric
