What is an expected cost for the end user? For the gear like this I personally would pay no more then $100-$150. But I see that you allow $50 increase just for safety. Yet another question.

However if both networks use the same parameters but coordinate the IPs in order to maintain using unique IPs for each device then the coverage, size and range of the mesh network increases. Then there will be only one mesh network that just grows. I like the idea of a large common mesh network - the mesh becomes a common communication infrastructure that can be used by everyone - NGOs, individuals, communities, entrepreneurs . On the other hand technically there is no problem separating two or many meshes operating in the same area (using different channels and ESSIDs and IBSSIDs). Things get slightly more complicated if you want to set up gateways that are routing from one mesh into the other and vice versa. Then you clearly want to separate the meshes by using non-overlapping sub-networks.

But what if two mesh networks with overlapping IP networks will "meet"? Won't this cause a mess in the networks? I has not experience with Mesh networks, so I may ask a stupid question.
