Not necessarily, the design works for all OSs and is very powerful.

Well, they talk about the interface to the kernel, and their nested
process model can provide layers oin top of this very efficiently. But
they don't talk about a high-level OS interface because it is up to the OS
designer using the model to provide this. You can implement as a
posix,win32 as well as bibEng's 'generic' design with the model, and even
all together running simultaneously on one machine or network.

Ghostview exists for Windows too. Perhaps you could get it at
www.tucows.com or so.

Well, I use Linux anyway, and sometimes NT. But installing Linux just for
this purpose...

I'm not really sure of what the best model is. I'll study some more models
and think of some things, and send a 'report' ... But anyway, I think you
should really seperate the kernel design from the design of the
higher-level OS services.
