Not sure if these numbers are the best to go by. Freifunk surely has the most setups. I might be completely wrong on this but I think most Freifunk installations are isolated, i.e. single-node with e.g. the local DSL as upstream. I wonder which of these have nodes with no cable-bound upstream or at least actually used interconnects with other nodes.
