Thanks for that info IanPJ - one of my current "good causes" is trying to get a group going to develop a social enterprise operated city-wide wirless system for Oxford and we are really now looking at WiMAX so I had only gleaned from WiMAX Forum and places like that that Freedom4 had the whole lot - good to know I might have two people to play off agains each other for spectrum renting!  Though I remain a bit pissed off that I have to buy it from somewhere else since it's "already ours" in my opinion!
