I really doubt it would become a one-click privacy measure: If you like to participate in an onion-routed, privacy enhancing, anonymity network, why put it in an browser?
A browser accesses that network, it is the weakest and least point in that setup.
There are so many ways to track an individual, independent of the network, with java-script, extensions, addons, plugins, client-side-caching that even if tor becomes a feature in firefox, the slightest unmitigated problem, even your behavior may compromise your privacy.
The article fails to make a good distinction for the different challenges of adhoc, infrastructure and privacy enhancing or censorship circumventing mesh networks.
Several others and I run a small (50 nodes) mesh network in my area, and it works fine for:
- enhancing WiFi access for all contributing nodes to an area which has limited or no coverage.
- providing fallback uplink connectivity for contributing nodes.
Infrastructure mesh networks are easy split into interconnected groups to avoid performance problems, and are still mesh networks, were a metropolitan area is covered by one ore more meshes to add redundancy and avoid scaling problems.
