I've re-read the document carefully and compared with my previous
comments. All my comments have been addressed. I particularly like the
elegance of the new algorithm which defers much of the work to RFC
6724. Implementation would be straightforward. The example is very
good.

One comment about this part:

   For efficiency, the PCP client SHOULD use the same Mapping Nonce for
   requests sent to all PCP server IP addresses.

I suggest rewording for clarity:

   For efficiency, the PCP client SHOULD use the same Mapping Nonce for
   requests sent to all IP addresses belonging to a single PCP server.
Different Mapping Nonces MUST still be used for requests sent to
different PCP servers.
