A method occured to me that obviates the need for public-key cryptography as a method of receiver anonymity in a dining-cryptographer network. I'm *sure* someone has thought of this before. I don't, however, have access to netscape or mosaic just now to search the archive with. If this topic or method has come up before (if you know of it, you'll know what I'm talking about; if not, and noone has come up with it before, which I doubt, I'd still like the patent ;-) and one of you guys has the relevant messages handy could you send them to me? Don't go through any great trouble, you understand... Phil
