Well, just using the 5GHz DFS channels in 80MHz or 160 MHz wide chunks would be 
a huge improvement, not many people are using them (yet), and the wide channels 
let you get a lot of data out at once. If everything is within a good range of 
the AP, this would work pretty well. If you end up needing multiple APs, or you 
have many stations, I expect that you will be better off with more APs at lower 
power, each using different channels.
