I think that the better way is to actually have each open have a
different minor number.
i.e. each process opens a different copy.
The way to achieve this best is with cloning devices.

Is there a possibility of a generalized interface where any linux kernel module
could be loaded, in the event that the linux emulator were loaded? Or would
this require running the linux kernel in RAM, and therefore running two virtual
machines?
