I get that, but Windows has its own way of doing something similar on 
the local screen. A Windows applications will issue some instructions to 
draw a window on a screen. It would have been nice if Microsoft had 
thought of a way to issue those instructions on a remote PC/terminal, 
just like with X-Windows.

No, but with a Unix or VMS system, applications with a GUI interface 
don't know if they are run locally using a graphics card, or remotely on 
a X-Windows server.
