Hi Sean,

I only can cover Europe in this statement, but I think it is certainly easier
for you to manufacture some kits for the ISM band (as a ham you may weep now,
for these are most certainly inside or next to HAM bands, e. g. 433MHz). These
kits may fall under a kind of "general license if by design you do not exceed
some limits for TX power or antenna gain - antenna directivity is also an issue.

So using 433, 886 or 2400 MHz will perhaps give you an easier life in the US of
A also.
One comment on your project: I think you are doing a great work, even I am going
to wait for the possibility to download the complete file. Lots of people will
profit from this work. I am also a HAM and my work is primarily RF circuitry,
and currently I am working on a compley book on most aspects of spectrum
analysis, covering schematics, methods, applications and theory. Benn writing
for 4 years now, phew.

So the best of luck for this project!
