Ember:
different view for authenticated and non authenticated user
(authenticated user sees root directory, non-authenticated user sees shared directories)
buttons for: delete / revert / rotate / share are only available for authenticated user
application initialization is deferred until session is downloaded
every controller has session injected

Django:
settings.py - DEBUG=False, ALLOWED_HOSTS is set
for non-authenticated users directory and subdirectory apis are filtered to list shared directories and their descendants
