Wrong market?
For backhaul from base stations, surely there are very few locations where satellite is the best option: either fibre, or a microwave link to another base station with a fibre connection. For filling in coverage blackspots directly, though, it would be great: just have handsets "roam" onto this constellation as a fallback, as Thuraya handsets do now. Putting this lot in orbit, only to have handsets still reliant on a piece of fixed infrastructure to get a connection anyway, though?!
