Yeah, as I said in my main comment, there are still things that need to be done. One of them is strong quotas. We plan on having it in the near future (we are also running a service, EteSync, using Etebase) though I think it's not an issue that should prevent you from getting started. :) As for migrations: that's a tough one, and we indeed don't have an easy-to-use mechanism yet. I mentioned it in another comment: the API at the moment is powerful and used in production, but it's still missing some goodies to make the developer experience even better. As for including every migration in your application bundle: yeah, well until you consider an old version EOL. It's the same challenge Microsoft has with Office, and every app has with their local storage.
