Say, that's a lot of fiber. Given that modern fiber can carry few TBps,
and hollow core fiber even more, what are you going to do with the
bandwidth? What's wrong with LoS and wireless for the last mile?

How much connectivity do you need? Few kbps from any point of the world
for anyone who can fork over a few $100 for the wireless receiver should
be doable right now for two figure gigabucks. If the user base would
scale, it would be even cheap.

transfer services.
