I am not sure what you mean by "auto-restart script" in this context. As I
see it, I have two options:
1. Use a single server-side process that shows and hides its graphics
window when the client connects and disconnects respectively.
2. Use two server-side process: an OpenSG cluster server process and
another that fork(2)'s and kill(2)'s that process when a client
connects and disconnects respectively.
Give that, it is a complication in the sense that it adds more code and more
places for things to go wrong. If my intended use of OpenSG is not going to
be supported, then that makes the decision to add that code clear.
