Brooke,
What is the problem? Just license your driver as GPL. Result, no more
legal problems.
The advantage of this approach is that you then get to use your device
with Linux. Alternatives along the lines of what you are considering are
not worth the effort by yourselves, and certainly not worth our effort
helping you.
Kind Regards
