	Regular old PostScript supports color just fine. You can specify
it in RGB or HSB formats. Grey-scales are supported with the setgray
operator. I *think* Display PostScript will have an operator for the CMYU
color model as well. Sun NeWS does wonderful things on a color monitor.

	The thing I'm skeptical about is how Next Step etc. will fit
with X11. I'm not sure X11 can be implemented for NeXT unless you go
directly to the display hardware. I don't think Display Postscript supports
the traditional Rasterop combinations required for X. An IBM official
quoted in the San Jose Mercury a few days ago said IBM would start
selling Next Step as an option to AIX sometime next summer when NeXT begins
volume production. Presumably they must have some idea about how to make
it all work since AIX is supposed to support X11. Maybe a merged server
like Digital.

	Also, does anyone KNOW how network transparent the NeXT User-interface
mechanism is? Is Display Postscript network accessible. Is the NeXT window
system network accessible? What if you write a NeXT Step application that
uses sound (NeXT sound kit). Will that interface work across the network
or will the sound come out on the wrong box?
