This is a bit pessimistic. Sure, one would have to write a PS
interpreter, but that's not too bad (I speak having done just that),
or snaffle a free one (like GhostScript), but if the PS file produces
output that makes sense for DVI (ie characters, mostly) the conversion
wouldn't be impossible. Even arbitary PS->DVI is possible (one could
alwasy use the '.' as a "pixel" and do all the scan-coversion - one
TeX plotting package does this).

On the other hand, I don't know of a program that does it.
