Another design issue to take into account in building a payments mix system
is that, unlike a message mix system, there is (at least in the United
States) an obvious "legal" (as opposed to technical) attack against payment
mix machine operators. Whereas message remailer operators are not obviously
doing anything that could expose them to legal sanction, a payments mix
machine operator could face a fairly plausible money laundering charge.
The obvious implication, then, is that a payment mix should to be designed
to conceal the identity of the operators of the nodes, whereas this is
merely an optional feature in a message remailing system. Always assuming
(never safe on this list) that the parties involved have pretty standard
risk tolerances and are subject to US law or can be found in sympathetic
jurisdictions.
