looking for an implementation

I'm looking at creating a "server-side" parallel port driver for a system that wants to look like a parallel port -based printer. Some (probably dumb) questions:

1. Should the existing parport arch be the right way to do this? I suppose I'll have to write low-level support for the particular device/chipset, etc.

2. Or perhaps a simpler kernel driver which handles just the minimum needed to implement the "server"?

3. Does anyone know of any examples of #2?

4. I suppose that (at least on an intel machine) a user-mode program with ioperms might be able to do this, but I'm on ppc405. Is this still a possibility on ppc?

any observations or comments are appreciated
