Only if you think "everybody hiding behind a NAT" is workable - in particular,
if you've got enough hosts that you're using up most of 2 /16s, you probably
have enough machines that might want an *inbound* SYN packet once in a while
that NAT isn't a really good idea.  Maybe if you're a corporation where
98% of the machines really shouldn't be accessing the Internet at all *anyhow*,
but if you're someplace where "Yes, you can get to the Internet" is policy,
you shouldn't be getting into the "but we're not letting you to *all* of
the Internet, just the things NAT works with" food-fight.
