I don't think that the FCC is interested in swapping spectrum. They are all for bringing internet to the people, but they aren't going to give up billions of dollars of spectrum to a company that tried to convert cheap spectrum into premium spectrum. No, it's not lightsquared's fault that GPS is spilling over into their spectrum, or that using their spectrum would cripple the GPS devices, but they bought satellite spectrum and tried to convert it to terrestrial spectrum. It was a good idea, but in the end it didn't work out.
