I'm not sure if I understand you right, but it sounds like you think I
was saying that Tor is only designed for sender anonymity, and that
sender anonymity isn't useful in general. I wasn't saying either of
those things.

My point was much smaller in scope: remailers have tried to provide
sender anonymity for email, but in the current climate that's useful
to fewer people than unlinkability for email, which a remailer-like
system could provide more easily than sender anonymity.

By all means let's build that remailer-like system on top of Tor, if
it can be done in such a way that the low-latency and high-latency
traffic share anonymity sets.

If on the other hand it's effectively two different networks sharing
an implementation then it might make sense to build a separate system.

Cheers,
Michael
