Sure, as you say, NextStep used Display Postscript as the window  
server (and, I believe, so did Silicon Graphics, before they went to X).

My sentence was sloppy, I should have said they were using a  
Postscript engine.  That said, I was mostly thinking about the Mac apps.

Yes, I wonder if the ability to hardware optimise the current  
approach was also a big consideration, or just a fortuitous result of  
a licensing-driven decision.

IIRC, Display Postscript was difficult to optimise with hardware,  
although I do seem to recall some talk of hardware.

Whatever is the case, the current approach seems great for hardware  
acceleration, and I don't believe many people are missing true  
"remote display" capability.

Cheers,
Ashley.
