It seems to me that a fixed mesh wireless network is just like the internet. The routing protocols will be based on the same principle (end-to-end, dumb network, smart edges, route around damage). The overall graph will probably wind up scale-free, with wISPs acting as hubs. With mesh, there's a possibility of a lot more exchange between different networks, since that's essentially the point, but these exchnages will behave like traditional IXs. Like the traditional internet, I don't really see the need for a lot of complicated payment schemes to reimburse people for their bandwidth -- instead the system will just route around problem nodes, by cutting them off or throttling them down.
