 P.S. I don't know exactly how mixmaster works, but you could
 really mess up traffic analysis like this.  Remailer#1 
 gets a digest with say KByte plaintext blocks from different
 messages encrypted to it.  It can unwrap this and rearrange blocks
 into each whole message.  It now has a message pool from
 packages various people sent it.  Most have onward destinations
 to other remailers, and it repeats the process of chopping up
 messages and sending them a digest of blocks.  This is a bit
 more than mixmaster currently does (I think), because many 
 people don't start as mixmaster packages at the user.  In and
 out are always the weakest points, because then blocks will at
 least assemble into messages from the same sender or to the
 same recipient.
