> The problem with low orbit satellites is the backbone connection speed. Yes, and system congestion, which you also mention. This is why so many different ideas are being considered -- balloons and solar-powered high-altitude drones to name two. But satellites, in spite of their drawbacks, at least in principle would have longer lives and wold present a lower per/subscriber cost. Because of the propagation delay you mention, satellites work very poorly with VOIP, in fact existing synchronous-orbit satellite methods won't work with VOIP at all. Future low-orbit satellites might be more acceptable, but propagation delay will always pose a problem for anything but terrestrial fiber.
