And how exactly do you propose to lock a dish onto a single satellite when they're moving around like that? Or is the idea to have enough of them out there that you don't need to lock onto a single bird, just have one in range?
Either way, it sounds expensive. Launching 7000 satellites isn't cheap, plus you have to have them reboosted constantly (500 mi is not a very high orbit, though it's better than the ISS) somehow. Unless they think they're going to get a ton of subscribers (and their system will actually be able to handle them all), it's not going to be economically feasible. Remember, they tried almost exactly this not that long ago with the Iridium satellite-phone system. It was a complete failure, and while it's still in use, the company that built and launched the satellites went out of business and it all had to be sold to another company for pennies on the dollar; they kept it going because their start-up costs were so low and they didn't have much of an investment to recoup. That doesn't sound like a good business plan to me. The only commercial satellite services that have been successful have been ones using GEO satellites, like DirecTV, since you can just launch one or two satellites and get coverage of the whole USA and not have to worry about boosting or replacing it frequently. GPS has been successful, but it wasn't commercial at all (the government does it for military purposes; we're just all benefiting from it), and even it only has a few dozen satellites.
