I have a shorter-term focus than Nick's proposals for digital coupons and cash. Here's what would be on my cypherpunks wish list: Improved remailers: The ability to handle reply messages; the ability to register pseudonyms of the user's choice, which get mapped to a user-supplied encrypted remailing block (this is Eric Hughes' model); true Chaumian "mix" functionality, with message batching so that in-to-out mapping is lost, including message padding so all messages are the same size. Remailer standards: An ad hoc assertion of standard remailer commands which all our different implementations will support. We could have a SIG just to discuss this. I don't think it would take long. Remailer proliferation: Build remailer software into some widely used mail packages like elm, metamail (which provides MIME support), emacs, etc. Digital cash: We badly need some implementation to start playing with; some net-based game which uses the digital cash. Digital postage stamps for the remailers. DH: I'd like to see more DH-based comm software so I can log in from home to my work or school computer and have an encrypted link. I know we have a version for the Amiga; I'd like to see it for PC. I'd also like to see an email program which used DH so that there would be no danger of coerced key exposure. Cryptophones: PC/Soundblaster or Mac based encrypted comm software using 14.4 Kbaud modems. This is a fairly daunting list, of course, but perhaps we should re-orient ourselves to be a working group more than a debating group. Split off sub-groups, get people to volunteer for each one, put one person in charge, have him make weekly or monthly reports to the main group. Hal Finney hfinney@shell.portal.com
