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.
