This depends entirely on your definition of "cheating". Basically, my
proposal (which I think crossed in the mail with yours, so I'm not
claiming that you misunderstood it -- in fact you anticipated *most* of
it, I think) was to charge once for entry to the "system", and to
include in that charge as many "hops" as you feel are necessary. No
cheating involved -- the truly anonymous hops would only be accessible
from within the "system", i.e. from a similar anonymous remailer
"inside" the system or from one of the fee-for-entry systems. If this
is the charging model, then the objections about knowing the chain
length, etc. all go away.

Not that much, just a revenue sharing arrangement based on income and
volume. Consortia do this sort of thing all the time, though most
consortia aren't formed in quite the atmosphere of paranoia that often

Actually, I think this could be serialized -- you could design it so
that you could use free remailers either before or after the consortium
members, but once you left the consortium system your message would have
to somehow pay to get back in again. That would be a mess, and not my
preferred way to do it.

Yes, it is is true that if digicash starts working for real money, it
will answer your objections quite nicely. However, there are lots of
objections to that sort of system, too, they're just different ones. As
both the FV and Digicash folks have pointed out many times, we have very
different technologies that fill very different requirements, it's not
an either/or choice. I think you could build interesting anonymous
remailers on each system, too. -- Nathaniel
