Actually NFSv4 almost forces this structure on you. You have to have a kind of 
"root" NFS share which has a magic ID of zero (forget the exact incantation) and 
then all the other shares you actually want to make are forced under that share 
with appropriate filesystem linkages and permissions.

I could never get this working. Ever.
