The idea is to drop all !NFS packets (or even more specific only
keep those NFS packets that belong to the critical mount), and
everybody doing critical IO over layered networks like IPSec or
other tunnel constructs asks for trouble - Just DON'T do that.

People are doing I/O over IP exactly for it's ubiquity and
flexibility.  It seems a major limitation of the design if you cancel
out major components of this flexibility.

I really can't take this work seriously when I see things like this
being said.
