Last time I looked at the VNC code, it required video hardware. It works
by reading the video buffer. No video card, no video buffer, no VNC.
There is a dummy video buffer built into the kernel but it is quite
literally a black hole; it only shows black.
This is as of a couple of years ago, so perhaps VNC implements some sort
of virtual buffer, although that would require a huge rewrite of libvnc,
or the kernel has implemented a functioning virtual buffer, which would be
much easier to do. Or perhaps an aspiring kernel driver guru could hack
one up. I've been told that it would be easy but clearly it's over my
head; a kernel hacker I am not.

As long as nobody gets hurt, a decent explosion livens up any experiment.
