COMMENT:
----------------------------------------------------------------------

I have these comments and questions:

1) There is no clear definition of what a PCP proxy really is. Section 1.
shows it as a pure signalling entity only w/o any NAT functionality (no
mapping functionality) but the document body itself talks about PCP
proxies having a mapping table (and also the possibility of not --
Section 3.4.1). Adding such a statement about the PCP proxy is or can be
to the intro or the terminology section is a good thing.

2) Section 3.1 talks about hairpinning:
There is a potential noteable issue in terms of network management: If
the PCP proxy is performing the hair pinning for the Assigned External
Address, the byte counters on the PCP server and the proxy will differ
for the Assigned External Address. This might be worth to note in a
network managment section (or elsewhere in the document).
