And not all regulatory information is public: as I wrote in a previous message:

I work for a company that has special regulatory permission to use channels

outside those freely available with tx power of up to 4W. This is a legitimate

use case that should not be forbidden by a new regdomain framework (I can always

hack around this, but that's just a hack, not a clean solution).



Regarding a user space daemon: keep in mind special use cases like NFSroot over WLAN.

Define "illegal manner". For me it is perfectly legal to use channel 14 in Europe with 4W tx power. I admit that this is a

special interest, but nonetheless perfectly legal.
