Okay, like I said, I am not knowledgeable...

Here are the versioins of VNC that I was refering to...
Follow the lead, if you think it is worth doing so...

Attachment one:
Announcing HWVNC: The HWVNC Server is a re-architected version of the
Unix Server. This allows the VNC server to run as a formal X extension
to an
existing X server. HWVNC uses the graphics hardware for rendering which
conceptually similar to how the Windows VNC Server works. A formal
interface has been added to allow HWVNC to be ported to different X
Currently, the HWVNC server is under development and ports to HP-UX and
Linux are planned. At this time we would like to solicit interest as
well as
feedback. We are hoping to make HWVNC available in the future.

and Attachement 2 (a reply to the above)

How is this different from xf4vnc available at http://xf4vnc.sf.net ?

xf4vnc is vnc ported to XFree86 v4.x and has the standalone Xvnc and
a vnc.so module which loads into the XFree86 server for exporting
the local hardware accelerated display.
