As John mentioned there's the concern about that the parallel port
and/or driver might get upset. Kay also mentioned a while back a bunch
of issues in doing this, e.g. chaining devices on a parallel port. Check
the archives. Of course, should you have a patch that does this it's
worth considering especially since WinXP proves this is possible. 

OTOH, as few people actually use parallel ports these days is this worth
looking into at all?

Cheers,
David
