In addition, there are several pieces that can be used as building blocks: 1. Federated / self hosted systems such email, newsgroups, RSS etc. Can be used, perhaps using something similar to DHT that can be used to locate images. 2. Bittorrent, webtorrent or a similar system can be used to spread data around and serve the data 3. Interplanetary file system - p2p network for storing and sharing data
