The perfect testbed for a p2p or federated social network to supplant Facebook. Or any other thing where we need to cut our dangerous dependencies on Big Internet (e.g. Google, Facebook). Imagine a p2p social network that worked more like messaging. Your posts, instead of going to and having to trust a central keeper (e.g. Facebook), would go directly to recipients. At most we'd need generic store-and-forward services if we want to assume users won't be running computers that are up most of the time. We could just piggy-back on the email network, broadcasting posts to your friends via PGP encrypted email, with some special subject prefix or header, so your mailbox rules can keep them from cluttering you normal inbox, and so your social network client can pull, decrypt and display them in your "news feed". Or we could use the BitTorrent protocol or similar for distribution. Again, PGP encrypted so other nodes that aren't the recipient of your post could still act to store and forward.
