As a teacher I'd like to be able to open an Ocaml Graphics window on each of my students display.
It's not possible with one instance of Ocaml, because Graphics.open_graph does 2 actions, 
opening a socket with an X11 server and opening a window on this server -- further instance 
of open_graph will only do the second action with the previous opened socket.

Perhaps will I have to rely on another mechanism to replicate windows over displays.

Marshalling is very handy as a way to botch things like this together.

Can CamlIDL be used to generate type-unsafe bindings?

Would running a VNC server on your computer and a VNC client on each
of the students' computers fit the bill?

You might want to migrate to a "proper" solution sooner rather than
later.  After all, you might also soon want to add buttons and menus.
Have a look at lablgtk2, here:

It supports a very capable canvas widget.
