In order to extend the write path all the way to the end user, we would need to fundamentally rethink the way we build many of these systems: moving away from request/response interaction and toward publish/subscribe dataflow [27]. I think that the advantages of more responsive user interfaces and better offline support would make it worth the effort. If you are designing data systems, I hope that you will keep in mind the option of subscribing to changes, not just querying the current state.
