We could certainly do a lot, and the progress of the 802.11 series with 802.11n attests that. However, there is a small 
problem with the open mesh type of solutions. As the density of mesh nodes increases, the range of each radio has to 
decrease. That works fine for short range applications currently served by Bluetooth and 802.11. But if your goal is to 
build a new internet, you have a problem.

Connecting short range radios to build a long range network is a lot like driving long distances through surface 
streets. It can be done, but it does not compete well with railroads, airplanes or freeways.
