This is something that we could easily make happen on a neighborhood scale. And it is not too expensive to connect thousands of neighborhood networks into a high-bandwidth global network with very, very high latency (by physically transporting data storage devices between such networks via drones or just in our pockets; ). But for something more reasonable - and easier for average people to make sense of - maybe track down Ramon Roca the next time you're in Spain and see if you can pick his brain.
