TeX isn't set up to do this sort of thing, for hysterical raisins.

dvips couldn't in fact deal with a dvi file on stdin, because it needs
to do random access to the dvi to generate efficient postscript output
(it goes so far as to have a special diagnostic "dvips: ! DVI file
must not be a pipe").

So the best you can do is to write scripts that emulate the DOS way of
doing pipes, by writing stdout to disc and then faking up that file
name as an argument to the next command along the `pipe'

All in all, hardly worth the candle -- you might as well write a
script to do the job straightforwardly.

XXXXXXXXXX

At least this won't work: dvips working as a filter (option -f) wants
to see the input (see man dvips).

I guess you have to use temporary files.
