I have just read that FCC regulation.

It doesn't prevent open-sourcing the code. It does require that each
software-defined radio must have some kind of authentication mechanism
to ensure that unapproved software cannot be loaded on to the device.

It seems to me that distributing a binary, which is easily modified by
users, (as proven by all the game patches and application cracks out
there), does _not_ satisfy the FCC regulation.

The only way to satisfy the regulation is to have an authentication
mechanism of some kind, so that the radio will not operate with
unapproved software.

If Intel have not implemented an authentication mechanism, then they
are not compliance with the FCC regulation as I read it because it
won't be long before some enterprising user patches the firmware and
makes the radio behave in an unapproved, possibly RF unsafe manner.

If Intel have implement such a mechanism, then regulation is no excuse
for them to not release the source code.
