For one thing I hadn't heard of it before now :-)

I would need to test and see what it recommends in real-world conditions. It 
seems designed for setting up a single AP (although it really shouldn't try 
every 2.4GHz channel), but when trying to pick channels for a bunch of APs in an 
area, I see nothing in the documentation that would prevent every AP from 
picking the same channel because it was marginally better when everything is 

Then when you start to see heavy usage, the situaion will have changed 
drastically and you would have to take time away from servicing clients to scan 
other channels (during which time you are not transmitting normally, so any 
other APs doing a survey during the same time would get a faulty view of what 
the conditions are), and would the system converge to a stable setup, or would 
it always be shifting traffic.
