That and nobody actually knows how to make mobile adhoc mesh networks beyond toy demos. I think NDN is probably the furthest along based on my reading between the lines of some routing algo papers coming from UCLA (read: .mil applications). I'm personally trying to make micro clouds (or mist computing if I'm being cheeky) a little easier and continuing research into MANets because I think its a really interesting problem that there's very little incentive to solve since the profit potential is tiny. I think a lot of this is applicable for making websites that can't be deleted, but like you say, the social organization comes first. Without the will to maintain the systems, no amount of tools will make a difference.

The infra meshes in berlin and elsewhere are basically volunteer-based wireless ISPs and can't be run without people willing to put in the work. They also aren't that much more resilient to disruption than a typical corporate WISP like starry or whatever, its just theoretically possible to have a community owned/operated setup because the infra is relatively cheap. No Se Vende Mesh is a project that was already happening in LA when I got here and I'm trying to be supportive. Some of the volunteers are struggling with motivation though because, well, its LA and organizing is hard.
