<P>I think that a step in the right direction would be to have a shared

|

library providing the same functionality as /dev/parport, and have
|

the library use the native OS support if available, and fall back to

inb/outb or whatever, failing if not root.

<P>(For the special case of collection IEEE 1284 Device IDs, there are

other fallbacks to try first involving /proc, and so this should be a

part of the interface.)
