Hello Tassos,
   Thanks for your comments.
The scenario we had in mind when we wrote this document is similar to the one you have just described, but the PCP is not on the BNAS it is external in the Service Provider's network and we want to be able to have subscribers of the same NAS using different PCP servers. The reason why we would like to use radius is because we would like to be able to tie together the PCP server information with the subscriber's profile stored in the Radius server.
If we don't have RADIUS part, we need to pre-provision the NAS with the PCP Server name, to be used in the DHCP option for each subscriber/group of subscribers. Please see attached slides.
If you think that more explanations are needed in order to clarify the use case we can add more text in the draft.

Thanks
Roberta

I am thinking of a similar implementation in our network, but after
looking at the doc i couldn't find any clear example of usage.

i.e. If you can define a PCP server locally on the NAS (DHCP server),
why do you want to supply it through radius too?

In our case, we want to differentiate service per subscriber or group of
subscribers (in terms of port mappings) and also have the capability to
have subscribers of the same NAS use different PCP servers in the future
(this also helps in testing a new PCP server by a limited number of
subscribers).

So, do you think a paragraph could be added regarding actual use cases
of this attribute?
