If you can start ssh on the remote end, set up your ssh so you don't
need passwords. Then just have the remote end call you. You can then
tunnel back into the box. I forget the exact incantations, but it has
to do with forwarding local port 22 to remote port XX22, then ssh to
localhost:xx22.
Now you have to watch your transfers; you are tunneling TCP over TCP
and that can be bad juju. Large transfers are likely to fail and
possibly saturate the connection on the slower end. (TCP over TCP can
get into a state where it continues to retransmit requests for
retransmits, and if you're really unlucky the whole thing will
snoball. Google for this on the web.)
I can't recommend getting in trouble, though... :-(
