I see some analogues in Sandstorm.io, for the web: they’re self-hosted web apps, where instead of the app being the atomic unit, each document (“grain”) is separately managed by sandstorm, and there’s a separate instance of the app running for each document. It pulls things like security and access control up a level, and will have even more benefits as sandstorm grain management matures.
