I'm not aware of any existing version of Xvnc supporting the GLX
(OpenGL) extension.  You could construct a new Xvnc from X server
sources that support GLX, doing the OpenGL rendering in software on the
server side.  This would probably be quite a bit of work but would be a
valuable contribution to the community.  You may be able to get your
application to do software OpenGL rendering.  I think there is a way to
do this with Mesa, possibly requiring a recompile of your application.
It would probably be the easiest way to get your app working within VNC.
A really cool solution would be to create an OpenGL encoding for VNC,
complete with a VNC viewer which supports hardware rendering along with
a VNC server that does software rendering for clients that don't support
the encoding.  That would be a pretty big project, though.
