Each village might have 1 Raspberry Pi attached to a large hard drive and a solar panel, which stores everything — the village library. Each mobile device would only have to store the subset of data currently relevant to that person — like a backpack. Maybe there's also an Endless Computer at home keeping the data important to you long term: family history, photo albums, newspaper clippings — the home bookshelf. (In Scuttlebutt terms, the village library is a Pub; the home bookshelf is a Scuttlebot following only your immediate family and friends; the backpack supports out-of-order messages and discards anything more than a few weeks old.)
