In the distant future, I'd like to separate the rendering bits into a 
separate library and have the current VncDisplay widget just be a client 
of that separate library.  Then you could easily have an OpenGL or SDL 
front-end.  I'd like to do this all around GObject though so I don't 
foresee a glib dependency disappearing in the foreseeable future.
