For the most part I like this.  It takes emotional trigger words out of 
it.  However, I would suggest focusing on Internet connectivity and away 
from all potential uses of NAT.  I believe the primary objection to NAT 
is in a general-purpose Internet context, and other more specialized 
uses might be less objectionable to some.  So something like;

    Use of NPT66, and NAT66 as a general concept, are NOT RECOMMENDED in
    the context of general-purpose Internet connectivity.
