Many years ago, long before wireless started to get going, there were a couple of companies that offered in-house networking over the existing electrical wireing in the house, good idea, but one of the main problem was noise (static, electrial), house wireing is not sheilded like network wireing. It was a great idea for its time.

The thing I would think might also keep it from going further, is fiber. Fiber network (around the world) will be the future for physical backbone and Sattelite's for the wireless. One of the things about fiber that I have read about, that there is techniques down the road to take the existing fiber threads and use the spectrum of light to channel data, i.e. red band would be a channel, blue band would be another ect... the only limiting issue would be the sending/receiving device (more spectrum bands used the more data can be sent at the same time).

blah, blah...well it was interesting to me anyways...
