This solution works near perfectly for me.  I needed to add a $wdir
before the filename, but otherwise it works!  To be clear, my rule is
now...

data matches '([a-zA-Z¡-�0-9_\-.,/]+)\.(dvi|DVI)'
arg isfile $0
plumb start window kertex/dvips $wdir/$0 '|' page

Very nice suggestion.  I will try to put this one in my bag of tricks.
