UltraVNC features data stream plugins.  There is a DSM plugin available that
provides RC4 (up to 128 bit) encryption.

Maybe I didn't understand your problem, but VNC and his enhanced
TightVNC both support SSH tunneling via OpenSSH.

From: http://www.tightvnc.com/faq.html#howsecure

How secure is TightVNC?
Although TightVNC encrypts VNC passwords sent over the net, the rest of
the traffic is sent as is, unencrypted (for password encryption, VNC
uses a DES-encrypted challenge-response scheme, where the password is
limited by 8 characters, and the effective DES key length is 56 bits).
So using TightVNC over the Internet can be a security risk. To solve
this problem, we plan to work on built-in encryption in future versions
of TightVNC.
In the mean time, if you need real security, we recommend installing
OpenSSH, and using SSH tunneling for all TightVNC connections from
untrusted networks.
