I wonder if LightSquared could have incorporated a GPS-like signal into their spectrum so that rather than interfering they would have enhanced the GPS system. Garmin, Magellan, Trimble, Tom Tom, et al would have needed to redesign their receivers, but I'm sure LightSquared could have helped with that considering the payoff if LightSquared's system could have been made to work.

I guess we'll never know.
