Ah, I see.  That definitely needs to be clarified.

Definitely so.  Replacing CPE with IHAS in the text will allow you to see
more clearly where you've assumed that the CPE and IHAS are co-located.

There's still something I don't understand.  If I'm understanding Steve's
and Markus' work correctly, HNCP performs prefix delegation to internal
routers over HNCP, and the internal routers don't proxy stateful DHCPv6 to
the CPE.  How does your protocol work in the presence of multiple links?
Or are you assuming that only nodes directly connected to the IHAS/CPE can
be advertised over your protocol?

Finally, what happens when there are multiple CPEs, which HNCP explicitly
supports?  Are you assuming that only one acts as IHAS?
