Datastore

Client applications probably want to store information locally in order to make things work. For instance, user preferences etc.

This can be stored locally but doesn't allow you to sync them (for instance, I had the problem when moving with PostBox.app from OSX to windows).

We could store things on the remote server as well inside a datastore. Each application can create their own datastore in which we keep data that can be synced with other instances.

[Q] how do we make sure that applications do not "share" data?
