It should work if the export is read-only *everywhere*.  If someone has write 
access to the underlying share, and writes to it while NFS clients have it 
mounted indirectly, Bad Things will happen, since Samba and NFS know nothing 
about each other's locking mechanisms.  Performance may or may not be good, 
depending on how you're using it.

Plenty of people have tried this, but very few carry it through to completion to 
write it up.  Most of them decide the inflexibility of the configuration is more 
of a pain than just setting up cifs (which is much better than the old smbfs) on 
the end clients.
