Elon Musk's satellite Internet?

[Commentary] Elon Musk -- the man who gave us the high-end, high-performance electric car and commercialized space travel -- has filed plans with the government to essentially rebuild the Internet in space.

Google and Fidelity recently invested $1 billion in Musk's SpaceX, in part to support the satellite project. SpaceX is the first private company to deliver goods to the International Space Station. It will begin delivering people there in two years. Musk's Internet plan is to launch about 4,000 small, cheap (by space standards) satellites into low orbit and test if they can bounce signals around the globe, including areas the Internet now can't reach.

If he succeeds, SpaceX or, more likely, its Internet spin-off, could compete with the likes of Comcast, AT&T, DirecTV and Dish. Wouldn't that be nice.
