Right. Bram and I talked early on about whether we should arrange it so
Tor and BT would work well together like this, and the conclusion was
that we shouldn't. BT is all about efficiency (getting data blocks from
various points directly to you, without a middleman), and Tor in that
respect is all about inefficiency (making sure the data doesn't travel
directly to you). So if you're willing to take the inefficiency hit from
Tor, then BT doesn't buy you much anymore.

The JAP team has implemented the Tor protocol inside their JAP client. It
lets you pick which network (Web mixes or Tor) you use. Their code is
in Java, and is free. I think it's working in the beta releases now,
but I haven't been keeping up with when they're planning to release it.

Yes, but it's going to take a lot of work. The key task is to let more
clients act like servers. But ideally, while we add more servers, we
still want some way of limiting the adversary from signing up lots of
servers and attracting lots of traffic (which would defeat anonymity).
So we're working on ways to scale without giving up much anonymity.
