The hard part will be getting enough such mobiles out in the market for the mesh to ever work and getting the price down low enough for people who are not ever so interested to buy it.

Presumably this is using something like Wimax so it shouldn't be difficult for other players to introduce compatible devices. In fact it should be possible to make a Wimax version of the portable Mifi routers that connect to mobile networks then you could use your existing devices and some kind of VOIP solution.
