NAT traversal was never a part of the protocol design, other than the
fact that NAT users can connect to non-NAT users but not other NAT users
(unless ports are forwarded.) BitTorrent uses TCP exclusively[*], and
there's no way that I'm aware of to get around the requirement for at
least one side to be able to receive incoming connections. All the
NAT-busting methods use UDP. So don't get your hopes up.

You could do some LD_PRELOAD trickery to socksify any client and force
all its traffic through a tunnel. But again encryption isn't part of
the protocol (well, it was in the original design but that's been
removed for years) so no client is going to do it natively. And doing
socks tunneling like this will most likely mean that you give up the
ability to receive incoming connections.
