Well, you would basically need to either capture the airtime usage
numbers on all the nodes and sum them to get the aggregate across the
network. You could capture that with Flent from all the routers, but I'm
not sure that's practical...

I think it may be easier to get the numbers from aircaps. This tool will
do that: https://github.com/cloudtrax/airtime-pie-chart -- talk to Simon
(I believe he's at Battlemesh) for details. You'd need your capture
nodes setup somewhere they can hear enough of the traffic go by to get
meaningful results, of course.
