I might set one of these up sometime this fall when I get a better net connection for my computer.. meanwhile, here's the idea: A payforuse anonymous id system. Someone would snail mail to me a money order, an login/aliasname, and a pgp SASE, encrypted with the public key of the remailer of their choice. (And the address of the remailer of course.) I would set up a mail alias which would take incoming mail, and send it off to the anonymous remailer defined by the user, with the SASE block thrown in the beginning of the message, and the To: From:, etc. lines added to the message using the "##" header pasting mechanism. Accounts would be debited according to the amount of traffic going through. Once all credit is used up, it would take another money order with the login/aliasname attached to refill the account with credit. In this way an anonymous persona can have a much more normal-looking email address, and the operator of the remailer is still ignorant of the anon-id<=>real-address mapping, to protect against subpeonas. This is just as weak as the remailer-chain used in the SASE block. The privacy of that will improve as the remailers improve.
