The summary:

It seems our users are going to be using ghostview from now on. Here
are excerpts from three very succinct replies:

1) From Ted Nolan (ted@ags.ga.erg.sri.com)
Sorry, you're out of luck. Sun's Openwindows combines an X server with a
NeWs server. NeWS is Sun's network PostScript interpreter (more or less).
No one else has one (everyone has just X or X+ true Adobe Display PostScript),
so you can't run Pageview (or for that matter any of the NeWS demos). Since
you can't run Pageview, you also can't run Answerbook, which is a real
pain.

NeWS support is dropped from Openwindows in Solaris 2.3, and DPS is added,
so in the future, you should be able to run Pageview on any Xterminal
that handles the DPS extension, but you still won't be able to run it on a
"plain" Xterminal (or X emulator).

2) From Steve Raffensberger (sdr@rdga3.att.com)
Pageview uses what's left of Sun's NEWS, which was based on
"display postscript". As such, it is kind of proprietary.
Regular X terminals and X emulators don't know anything about
it.

3) From Ed Strong (ems@ccrl.nj.nec.com)
NeWS is not X, it is more related to Display Postscript. Therefore
standard "pure" X servers can't support it. Sun's Openwindows support
both and and NeWS. NCD X terminals have an option you can purchase to
add display postscript to their X server.

End of summary.

My thanks to all respondents including those whose messages are en route.
