Well, there is no 'libnfsv4acl' library - as far as I know Linux only comes with libacl library which is POSIX draft only.
I use the nfs4_*facl command to manipulate those.
My personal opinion is that the current libacl library should 'understand' nfsv4 semantics, too.

If I submit a RFE against libacl package - how much success can I expect with implementing this?

Second question:
Simo said that re-exporting NFS is not supported. Why? It always worked fine for me - including file locking...
