Till,

I've looked over your "caxy" package.  Nice job!

Also see http://www.delegate.org/delegate/, which is a very nice "Swiss
Army Knife" of tunnelling and port forwarding using SOCKS. It does both TCP
and UDP forwarding.  The documentation is a fair translation from Japanese,
so takes a little bit of work to understand.

Less versatile is https://github.com/apenwarr/sshuttle, which uses ssh
forwarding.

Unfortunately, I was hoping for a bundled solution, so I wouldn't have to put
our users through any more work than necessary.  It's to bad that CSS is not
ssh tunnelling compatible while EPICS base, and the clients that use it, are.
