I think the key is that the File/Object service should be enabled similarly to how volumes are enabled,
With similar tenant scoping and granularity.

So a NFS export would be enabled for a VM much the way a volume is, with the only difference being
that a NFS export *can* be shared. But when it is not shared, it should be just as eligible for local storage
as a cinder volume is.

To the extent that this is not just a "migrate-to-local-storage" feature, it needs to be integrated with Quantum
as well. The network needs to be configured so that *only* this set of clients has access to the virtual network
where the specified exports are enabled.

This does a lot to solve the multi-tenant problem as well. Each export can be governed by a single tenant.
If the NAS traffic is all on different virtual networks there are never any conflicts over UIDs and GIDs.
