  It looks good.  I'd like to know if the PRE can relay messages from
the PAA to the PaC on a non-PANA port.  If so, that needs to be
addressed somehow.  Saying "use DTLS" might not be enough.

  If the PaC always sends packets from the PANA port, then the text
should be updated to say that the PAA only sends packets to the PANA
port on the PaC.
