Ghostview is not a postscript interpreter, it is merely a viewer on top of
ghostscript which does the �ostscript interpretation.

"commercial product" does not necessarily imply "proprietary software". It
may well be possible for you to base your work on GNU ghostscript, provided
you abide by the terms of the GNU General Public License); see
http://www.fsf.org/philosophy/ .

PostScript is AFAIK a trademark of Adobe, so if you want to term your
product a "PostScript interpreter", you probably need to negotiate some kind
of agreement with Adobe. Of course, you can follow ghostscript's example,
and not claim that the language you're interpreting is PostScript (TM).
