I suppose so. That hadn't occurred to me, actually.

It does need extending. Read/write could do IEEE1284 transfers, and there
could be ioctls for IEEE1284 mode negotiation and so on. Some way of
integrating with the IEEE1284.3 daisy chain stuff (when it's done) would
be good too. As would a better name.
I think work is being done on it though. (Phil?)

The main reason I'm against getting it into the main sources is that it
hasn't been properly tested. Not just "does the code work," but "does the
behaviour of /dev/parport00 make sense?"
