A wrapper around \executesystemcommand,

 \long\def\dostartPSTRICKS[#1]#2\stopPSTRICKS
  {\doifelse{\jobsuffix}{dvi} % will some day move to app as switch
     {\hbox{#2}}
     {\startTEXapplication[#1]{\usemodule[pstric]}#2\stopTEXapplication}}

for \startTEXapplication see
page-app.tex


\long\def\dostartTEXapplication[#1]#2#3\stopTEXapplication
  {\bgroup
   \bgroup
   \let\f!temporaryextension\c!tex
   \setbuffer[\@@texapp]%

     \startTEXpage[#1]%
       \topskip\zeropoint
       \setbox\scratchbox\hbox{#3}%
       \saveTEXapplication02% dimensions
       \box\scratchbox
     \stopTEXpage
     \stoptext
   \endbuffer
   \egroup
   \doifelse\jobsuffix{dvi}\donetrue\donefalse
   \executesystemcommand{texexec \bufferprefix\@@texapp.tex --once --batch}%

     \executesystemcommand{dvips \bufferprefix\@@texapp}%

\bufferprefix\@@texapp.ps\bufferprefix\@@texapp.pdf}%
%      \executesystemcommand{texmfstart pstopdf
\bufferprefix\@@texapp.ps\bufferprefix\@@texapp.pdf}%
   \fi
   \restoreTEXapplication % dimensions
   \doifelse\jobsuffix{dvi}\donetrue\donefalse
   \setbox\scratchbox\hbox
     {\expanded{\externalfigure
        [\bufferprefix\@@texapp.\ifdone eps\else pdf\fi]
        [\c!object=\v!no]}}%
   \setbox\scratchbox\hbox
     {\lower\ht\scratchbox\hbox{\raise\dimen2\box\scratchbox}}%
   \wd\scratchbox\dimen0
   \ht\scratchbox\dimen2
   \dp\scratchbox\zeropoint
   \box\scratchbox
   \egroup}


I suppose that works ok in mkii, but maybe not in mkiv
so the actually the best way is (imho) make pdf images  using traditional
way (latex+dvips)
and include them by \externalfigure
