    Main operations:
      - create metadata store if missing
      - launch / stop synchronizer process
      - list attach local folder to remote folder
      - query synchronization states of elements
      - query the operation log

    All operations performed by the controller are fast and asynchronous:
    the controller never waits for a remote network connection. All
