This is pretty impressive. Being able to decouple the user-facing realtime transport layer from the database engine is one of the main things which has been holding big companies back from adopting Firebase (due to Firebase's tight coupling with MongoDB and the associated lock-in factor). I imagine that eventually you would be able to hook fusion into any database engine or service you like - If you don't want to put your sensitive data on a public cloud, you could just use fusion as-a-service but host the Database part yourself.
