In both cases, I think there is an open question (raised by my regarding your draft) of whether we want to modify PANA so that the server will know that it is performing PCP authentication vs. network access authentication.  I think this could be important, if we want a single PANA server to be able to serve both purposes in a small network.  It is possible that the credentials/criteria used to authenticate a node for PCP will be different than for network access, isn't it?
