GhostNet: Off-Grid, Radio-Based Networks Partially Replace the Internet (github.com)

This is super interesting. Looks like it's not just an emergency fallback, but could be part of our daily lives. I doubt it'll fully replace the internet, but it could be a game-changer for rural or disaster-hit areas. The off-grid culture angle is cool too. Could pave the way for some more decentralized use-cases.
