I'd like the results themselves..for instance, just piggyback on whatever
supplicant is already doing to get periodic updates, and of course I'd
end up requesting some scans myself from time to time if a user wanted
an immediate update.

I was hoping it could be something like just listening for network-device
and route updates like netlink already supports.

Since scanning is relatively slow and expensive, it seems like a good
idea to allow re-using the results...

Thanks,
Ben
