So, you use a chain of anonymous-id's to set up your return-path?

Unfortunately, return-paths are not exactly the strong point of the current cypherpunks remailers :-). That is what much of the discussion in this thread has discussed: how to best allow for convenient but secure return paths.

Yeah; the only solutions I've seen so far either give you some persistence, like anon.penet.fi, or no replies, or have generally been pretty ugly, requiring rapidly-increasing numbers of messages to set up chains of anonymous IDs, or use broadcast, like the Blacknet "post to Usenet" or DCnets. AIR-MAIL may be a start. It seems to need something that supports a small but >1 number of replies to make a non-ugly system, which means either some kind of Time-To-Live or destruct messages from one or both ends need to be supported.
