A lot of applications are much closer to home. For instance, I've seen a few teams pitch the idea of building a robust, small-satellite network to serve as a platform for Machine-2-Machine messaging. I think enabling the global IoT industry is really going to unleash some spectacular applications. Internet everywhere is of course a popular idea that's being worked on. I particularly like the low-data rate, low monthly charge model that I've seen pitched. Seen teams pitch internet anywhere for as low as a couple of bucks a month.
