Not really.  Just to say that as a user of natd and one that knows how
fragile ipfw & natd are to passing packets I don't want to disturb things.
I want to see some people (other than me) experiment with this the natd

Native also covers NFS mounted /usr and UFS /, and Gordon didn't mention
that he had carefully looked at /etc/rc.d/* and the implications of
moving things.
