How would this work for apps that are multi-user, like email, social networking, or marketplaces? The Sandstorm data model doesn't really work when you're dealing with the data of many users besides yourself.
Federated networks! Your server will be able to connect to other people's servers through Cap'n Proto RPC interfaces (or perhaps other protocols, if you grant them general network access). So your social network app would host just your profile, and people would connect to it to get your feed, or your server would push your feed to servers of people subscribing to you. "Friending" someone would mean obtaining a Cap'n Proto capability to read their feed (but the user doesn't have to understand that).
There have been attempts to build federated social networks over the past few years, such as Diaspora, but they have not really taken off primarily because it's too hard to get users to run their own servers. Sandstorm potentially fixes that.
