I think this misses the point completely.

The NFS protocol implementation is fairly solid.  After all, it's
based on Rick Macklem's code, which is in 4.4bsd and FreeBSD as well.
As I understand it, the problem is lack of consistency between
the buffer and VM caches.  (Or something.)

Precisely, which is why talking about using AFS instead misses the point, too.
(Besides, personally, I find the costs of using AFS not worth the
hassle in an environment smaller than 1000's of users on 1000's of hosts.)
