Why not "charge" for the ability to send an anonymous message with the duty to have for a short time (maybe an hour or two) running on your machine a node in a remailer network?
User X on Machine A sends a form via HTTP (or a variant- SHTTP, HTTPS, etc.) to Machine B. User Y on Machine C receives an anonymous mail from Machine B. Suspecting User X, User Y sends a mail to be anonymized and sent back to himself to User X. User X's temporary remailer does as it's told. User Y now has a strong reason to suspect User X has sent the said mail.
If the "duty" cycle is 1 hour and there are 10000 users utilizing the network, that tells you nothing. All it does it confirm that User X sent a remailer message within the last hour. One could just as easily finger User X and use the same reasoning. And if one has to suspect User X in the first place, User X has already blown his cover partially (either by writing style or other leaks) -Ray
