[FreeNX-kNX] SSL tunneling

[freenx at mikebell.org]

How precisely is the SSL tunneling of NX implemented? If it's done with
SSH port forwarding, how are conflicts due to multiple clients handled?
If it's done over the main ssh tunnel itself, how does one have nxagent
read from stdin? Does it perhaps use the -X features of ssh? If so, how
does one reverse the connection order?

I tried looking over the source, but it's pretty hard to parse, what
with the options for various commands being embedded in the libraries
and such, and I wasn't able to find any documentation for the various
nxproxy options (the --help function just prints a placeholder sort of
thing).
