Yay, thanks for this.  I hadn't quite gotten around to doing it.  Next
question though, if you populate the supplicant with a bunch of
networks, shouldn't it use up to max_scan_ssids from the network blocks
(sorted by priority of course) when doing scans on it's own?  Or does it
do this already?  If not, that would be the  next step.
