I semi-recently worked on a P2P video distribution system (not like BitTorrent, that's not really suited to sequential content) - not that different from Spotify's old system. One of the things we ended up doing to support new release binge-watching was to have a predictive consumption led pre-fetched content cache for network neighborhoods. It wasn't a change-the-world difference, but interestingly, a lot of people do watch the same video content over a period of not that many days.
