Latency sufficient to support real-time applications?
I read that as "gaming". I do believe that knocks out all those satellite infestations being launched unless the players want to be slaughtered by lag... even at that minimum distance, the data still has to be routed after it reaches the ground stations, so they're ALWAYS going to be "underserved" compared to the rest of the population.
Besides - do we really need to make EVERYTHING in our lives vulnerable to sunspots and solar flares?
