I agree with Faisal here...

Our experience from the freifunk style networks in Europe is that a mix of 
backbone/mesh nodes
and layer 3 meshing gets the job done.
Why layer 3? Because you don't want it all to be a single layer 2 broadcast 
area :)
Your spectrum is just too valuable to send every broadcast message to all 
others in the network.
Combine that with BGP/OSPF/whatever backbone links which are built point to 
point (or point to a few multipoints)
with high capacity and you are set.
This way you can even have layer 2 meshes interoperating with different meshes 
or OSPF/BGP/IS-IS/whatever protocol
backbone networks.
