I thought more about this and this might not be required. I think a good way to find out about the exact requirements might be to look at what all do we need for this to work with Slash GraphQL. A user having their own Dgraph instance deployed in Slash GraphQL would not access data in another namespace (belonging to another user). Guardians (superusers) are the only users that might be able to access data across namespaces.
