Or one can send to alt.anonymous.messages, or wherever. And recipient(s)
can periodically download everything, and simply try decrypting each
message. I don't recall now whether remailer nyms worked exactly that
way. Maybe client apps depended on seeing recipient IDs. Or maybe hashes
of recipient IDs. It's interesting, but doesn't scale well.
