Display postscript is an extension that can only be licensed from 
Adobe. It is "normally" an extension on X-Windows. It consists of
a server extension where the postscript engine is added to the X-server.
The communication from the client side uses the X-window prototcol. From
the source side you can call procedures which sound the same as
the procedures in postscript (e.g. moveto, save). 
There is a utility, pswrap, that converts a ps file into 
C, this is also used for the interface lib.
As far as I know is the IBM RS 6000, DEC windows and NeXT the only 
implementation at the moment. But you can talk to Adobe to get a 
licence. But you better be prepared to pay..
For Windows or OS/2, I think DPS is too closely linked to X to run
on these tiny window systems.

It is really very nice to work with f you can run it on a fast
machine. I used it on a RS6000 530 server. Nice!

Hope to have helped you a little bit further,
