I asked GNS Wireless, RadioLabs and FreeWave Tech. if their gizmos could reliably communicate between a.) A HamWAN antenna on Lookout Mountain and b.) computer users living in a treed neighborhood roughly a mile away. Greg Corey at FreeWave Technologies replied "We specialize in long-range, non-line of sight connectivity for industrial processes. We can most likely achieve a link to the locations you described but the connection speed would be very slow. Our maximum throughput is around 1.5Mbps for a single point-to-point link. Generally speaking, this isn't going to be fast enough for general home internet usage." The others didn't reply. I hope that helps, or is at least interesting. Comments welcome. So, Kingsley -- Time is the fire in which we all burn.
