Sure, just set $PageEditFmt = ''; when you don't want the edit form
to appear.  But ohhhh, I get it, you also don't want the "page preview"
and other stuff to appear.  Just build a version of HandleBrowse
that gets its text from $_POST['text'] instead of from the pagefile.
Something like:

   function HandlePreview($pagename) {
     $text = $_POST['text'];
     $text = '(:groupheader:)'.@$text.'(:groupfooter:)';
     $FmtV['$PageText'] = MarkupToHTML($pagename, $text);
     SDV($HandleBrowseFmt, array(&$PageStartFmt, '$PageText',
       &$PageEndFmt));
     PrintFmt($pagename,$HandleBrowseFmt);
   }

   if (@$_POST['preview']) { HandlePreview($pagename); exit(); }

Sounds quite interesting -- let me know how it progresses!
