[ppml] IPv6 address as a Globally Unique ID?

This document does indeed state that their globally
unique ID will be an IPv6 address. ARIN, the NRO and IANA
should really send an official letter to the government
telling them that this is not an appropriate use of 
an IPv6 address.

For one thing, the rightmost 64 bits of the IPv6 address
are already sufficient for a globally unique identifier.
In addition there are models that the government could adopt
for creating a 64-bit globally unique identifier such as
the IEEE's EUI-64.

However, it is wholly inappropriate to use an IPv6 address
because these addresses are reserved for use by device 
interfaces which connect to IPv6 protocol networks.
