I'm pretty sure a loop device needs a real local file to back it. NFS isn't up to it (it's a stateless view of a filesystem, not much good for an OS layer that needs timely and reliable block I/O to a file as backing store). Have you considered doing the loopback mount on the remote system and exporting _that_ over NFS? That will work fine. In fact, we do that here.
