What about the one where he connects via a low earth orbit satellite constellation which has redundant ground stations in Hawaii, New York, Germany and India? Or any 4 points that actually fit on an orbit? The cool thing about LEO is that it starts around 100 miles up, so you don't have long speed of light delays or large transmit-power requirements. But you do have a huge geographic spread. In a developing country, it would be doubly-handy if a customer could use a terrestrial radio network when the signal is good and fall back on a more expensive LEO satellite when the terrestrial radio network has problems, all without disturbing the ongoing end-to-end connections. Yes. This is precisely where the routing challenges start to get exciting. Heiner
