The Adobe rep is right but his reason is wrong.  NeWS programs will typically
be full fledged applications using the input and canvas extensions of NeWS
to handle interaction with the user.  DisplayPostScript is output only and
doesn't even have any similar extensions.

However a PostScript described page will display equally well under
DisplayPostScript or using psview under NeWS.  Sun does follow the
PostScript standard (as of NeWS release 1.1).
