This helped me visualize how close LEO satellites are, as well as how far away others are (e.g. GPS).

Cool! Quick back-of-the-napkin indicates that the RTT for LEO satellites (at the upper bound) would be only ~4.7% of the RTT for GEO satellites. I'm sure there's much more to the story that I'm missing, but an LEO satellite should have a latency of around 11.75ms. In 2012, average US latency to Google was ~50-60ms [1]. Would bandwidth be the limiting factor?
