I guess what I'm getting at is, EMC2 compatible hardware usually gets
assigned a port manually with a config string and it seems even a
printer would need a manual configuration. I think the manual
assignments block any sharing by their nature, so I wonder if being
parport compliant really adds any value. It looks like Hostmot already
breaks compliance. Although ppmc looks like it needs it to share more
than one card on a single port. (uhg, my brain hurts)
