That's actually a good point IMHO, Marco. I was talking to another
remailer operator the other day and both of us remember seeing
somewhere in stats that a remailer was operated either on the same
hosts or by the same person/entity. I'd think that, if stats is
already pulling this information in, it might be fairly simple to do
what you're saying.

In fact, we should possibly go a step further: unencrypted mail cannot
flow through two remailers operated by the same person regardless of
the chain. So in my case, I operate both Oklahoma and Isis. A user
should not be able to send unencrypted mail as oklahoma,*,isis. This
could easily allow tracking and compromise IMHO.
