As being probably the first person who have raised the need in server-to-server copy 
in NFS (see slide 15 http://nfsv4bat.org/Documents/ConnectAThon/2008/managedstorage.pdf),
let me disagree with you.

Having end-user hat on me I can say, that over a decade we are moving scientific
data around the world with server-side-copy, or 3rd-party copy as we call
it. While we more-and-more use NFS (pNFS) for data access, we always need a
second protocol, like FTP or WebDAV, to perform efficient data movement.

I am not deep in kernel internals, but there must be a very good reason to block
such functionality in NFS. Such functionality will drastically simplify our
workflow. And I am sure, we are not the only users of it.
