Content-centric networking seems well suited for mesh networks, where instead of futilely attempting online communication across a network in continual flux, static information is opportunistically exchanged, with some ranking/reputability system used to decide which content to publish, and which to receive. Something closer to FidoNet than the Internet.

Another benefit is the possibility of not requiring battery-powered devices to be permanently awake in order to serve as router for other nodes in the mesh. It's easy to imagine a scheme where devices only wake for a specific window every few minutes to handshake with any interesting neighbour, synchronized to the device's current best idea of time (something that could even be derived from the mesh during initialization).

While it wouldn't allow you to watch every desired YouTube clip, in a scenario where freedom of information was threatened, such a network might be very effective for transmission of important information. One aspect that isn't clear would be how a user would configure their (space constrained) mobile device with a policy to filter the exchanged data, e.g. the ability to select regional news while excluding pornography, sports, or politically motivated content.

I think given software with the right UI, and some motivating application, technology already exists today in millions of pockets worldwide to make a network like this reality.

I think the desire to filter the content their device transfers is likely to be harmful to the intended use of the system; in a scenario where freedom of information is threatened, participants would want to carry state TV and sports in addition to regional news so that it's plausible (and even likely) that the reason for participating is actually to follow the latest football matches, not protest the government. That also means that the people who actually just want the latest sports aren't able to avoid spreading the region news, and everyone cares about football, while (in the situation where freedom of information is threatened and matters) only a significant minority of the population wants to protest the government.
