[ppml] IPv6 flawed?

Such a company would qualify for PIv4 and thus PIv6 because the policy 
counts _all_ hosts, not just publicly-visible hosts or NAT boxes.  You can 
get a PI assignment for a _completely disconnected_ network if you have 
enough hosts, though RFC 1918/4193 space is recommended in such a case.

That's why we have PI policies for both v4 and v6.
