Apparently nobody answered to this yet, and I forgot. Sorry :-)

That isn't going to work, for the same reason why serving the same NBD
device to all your clients isn't going to work -- unless the filesystem
you use on top of NBD has been specifically crafted to make it possible.
I don't know whether such a filesystem exists, though.

Not just 'can', 'will'.

Unless of course you're setting up a failover cluster where your clients
will use the NFS file system from one of both the systems, and only fall
back to the other one if the first one breaks down.

The amount of time between slipping on the peel and landing on the
pavement is precisely one bananosecond
