I was thinking of the Unix version, which can be integrated with SSH
to do encrypted port tunneling by default. The Windows server is
weaker in this respect and requires a lot more hand-holding. There,
compile the Unix version of the server under Cygwin and we are
on-topic again. :-)

As Ross Boulet has pointed out, encrypted port forwarding is a feature
of SSH and can be used to create tunnels for any other TCP/IP
protocol; or you could create a SSL tunnel with stunnel. What makes
TightVNC suitable for tunneling over an encrypted channel is its data
compression protocol (JPEG), which is much better than the one used by
SSH (zlib).
