Anybody looked at what it would take to do MAC/Radius auth in the wi/ath/wlan stuff?

Just curiuos if anybody's looked at it.  I still end up having to
use regular AP's for customer access just to be able to help
authenticate them.

If I could check their association at the very beginning, I cold
use FreeBSD for just about everything...

Anyway, just curious if anybody's looked at it.
