Noting that on unix VNC provides an X server, so if you could tell
that to disregard the normal startup and run without a display
manager etc. you could then draw onto it directly.
AFAIK it requires special X invocation to start it, or additional vnc server
program
(or for the matter, a special build of X server, in Debian a separate
package...)
started if the session exists already - x11vnc does it for you (why would a program like Vino
have to exist if this is achievable with just X ?)
Standard VNC is /completely/ separate from the standard X server on any
given system, except that some variant has the capability of "scraping"
a pre-existing window for support purposes. I normally start up multiple
copies in /etc/inittab, specifying what socket each is listening on; at
that point any activity on the console X server (or even the absence of
a console X server) is completely irrelevant.
So the issue isn't starting VNC and keeping it separate from the
console's X session, but is one of making sure that VNC doesn't fire up
the default display/window managers.
