As said, i have gone through this process for more than 42 of
the devices for my Femto OS. If this get serious, i am willing
to donate these device files as a starter under whatever license
we agree upon.

The most difficult part is to define a systematic nomenclatura
for virtualized access, which holds for all devices. I don't think
we can just take mine, because my area interrest was only
a small portion of the devices (and i use a java style 
camelCasing :-) I discovered, during the development 
(when i was adding more devices), that i was never completely
satisfied.

Of course we separate the device selectors and the device definitions ...
