SneakerNet allows local users to distribute digital content locally (decoupled from the internet).
The Little Free Library provides physical media to local users. Physical media (books, compact discs, etc.) is being replaced with digital media (ebooks, mp3, etc.).
Access to digital media is diluted by social networks.
SneakerNet nodes are public wifi access points serving digital media.
You can create a SneakerNet node inexpensively (less than USD$50).
