It would be easy enough to split the message by XOR into as many
pieces as you wish. This would be much more secure than an
every-nth-byte division, though it would increase total traffic
correspondingly. Taking into account the non-ideality of the
remailer net, using m-of-n secret sharing would be more reliable.
It's not clear to me that this buys you much, though. Encrypting
the message end-to-end will suffice to keep it private. What
remailers do for you is impede traffic analysis. Sending your
message in n pieces gives a traffic watcher n chances.
