Hi Patrick,
as currently implemented, the Scalatron game server opens a window on the machine where it is executed.
There is currently no built-in mechanism for providing a view of the game on another machine, other than via the limited bot view in the browser-based "sandboxed" game debugger.
Some folks reported VNC as a successful mechanism for remote game display, however, so you might want to look at that.
Hope this helps!
