So what's up with 802.11s? Or any other "stupid" link-layer protocols
which are not part of the WiFi stack? Is it not a mesh network?
In any case, I would make a difference between "mesh network" and "free
community mesh network". First one only references to technical stuff,
second one would refer to also philosophic definition such as
decentralized, bottom-up, etc.
