Um, that's nonsense.  There are numerous distinct NFS code bases:  Sun's,
which has changed significantly over time; the ancient Wisconsin code that
was available for 4.3BSD; the Macklem implementation in its NFSv2 
incarnation from Berkeley net/2; the Macklem implementation in its NFSv3
incarnation, which behaves significantly differently in some ways than its
ancestor; other Unix vendors' code such as SGI's and IBM's which is
occasionally updated from the Sun "trunk" but has diverged greatly over
time; the Linux implementation, which is probably the most alien and evil,
in its user-space incarnation, its version 2 kernel incarnation, and its
version 3 kernel incarnation, amd's user-space incarnation, and NetApp's

I'm sure I've missed some.

Again, that's not really true.
