The WLAN driver knows the bandwith it would use the next time for the link 
(based on signal strength and/or recent unicast transmissions), so we just 
have to find a way to ask without wasting lots of CPU.

In linux I would look at the nl80211 infrastructure, but we need an 
alternative for Windows/BSD.
