I was thinking of launching a kickstarter campaign to bootstrap a city-wide mesh network in my city. The idea would be to have a text-based communication network that works in emergencies, is censorship-resistant and encrypted. I could collect money for X nodes to cover the whole city by approaching cafes, bars, libraries or universities and asking them to contribute by setting up a node for them. If successful, maybe other cities would follow the example and the citizens of each would bootstrap their own networks.
