I thought about benefits of doing such an xserver.
It was not particularily meant for your specific target.
(You might want to describe it a bit more, do you?)

The screen layout might be arranged in whatever way you want,
i just mentioned this as a sample case. 
You on the left, your girlfriend with the USB mouse right. ;-)

possibly others might want to do so, at least its the simplest
way to make such things you want running.

Glut is a default library that covers any OS specifics from
your programming. And there are pretty lots of differences.
Thats why i paired it with the OpenGL standard. Else you
have to fiddle with wgl, aux, x11-basics, ... depending on
where you are.

OpenGL in itself is not complete in itself.
The main part that is missing is the surface management.
OpenGL in its core only a drawing interface.
