   Mesh technologies don't work except in contrived geographies. It all   
   comes down to the fact that radio signals with frequencies higher than   
   30 MHz or so don't bounce off the ionosphere. That means they are line   
   of sight only. If your phone's radio doesn't have a clear path between   
   it and the potential receiver it simple won't work.   
      
   Cell phone networks work because they pay the big money to get their   
   nodes up high above surrounding terrain with power and data. That's   
   really only feasible for mesh networks in coastal cities with mountains   
   or mega-cities where residents have access to the roofs.   
      
   Even store and forward doesn't help these "mesh" line of sight networks   
   when all the antennas are a max of about 2 meters above terrain.   
      
   I wouldn't bother. Which is to say, I've already spent years and years   
   playing with VHF and up IP and otherwise data networks over radio. And I   
   can tell you from personal experience: that little rise in the land, or   
   being in a little dip, is going to kill things. Mesh networks don't work   
   without big bucks being invested.
