I think this was me, or at least I've advocated that many people become "first class citizens" be being remailers themselves. There are thus no "sources" or "sinks" of messages...any Federales who pound on your door can be told "Oh, but I was just _remailing_ that message you traced to me."
Please excuse me if this has already been discussed... but... What about the trend of busting the sysops of bbs'? The recent Fidonet bust in Italy seems to support this trend. It sounds to me like any remailers remailing illegal stuff may get caught in the dragnet.
