Brain,

We have thought about this from day one of our document. This is the sub-section we have in our Optional IPv6 features section.

[8.2.  Optional RIPng Support
The CPE Router may support RIPng routing protocol [RFC2080] (Malkin, G. and R. Minnear, “RIPng for IPv6,” January 1997.) so that RIPng operates between the CPE Router and the Service Provider network. RIPng has scaling and security implications for the Service Provider network where one Service Provider router may terminate several tens of thousands of CPE routers. However, RIPng does provide one solution from the CPE Router to the Service Provider network for prefix route injection.]

I and more folks thought one home to another home communications were being discussed but actually what James was looking at was a single home and this home's networking.  We also had a disconnect with James because it wasn't told to us that there was a hub sitting behind the broadband modem and then a CPE Rtr is behind the hub.  We assumed the CPE Rtr was directly connected to the broadband modem. Now that all things are clarified and we know it's one single home being discussed, we will look into common scenarios that Service Providers have in mind and take it from there.

Yes, but if we conclude that it's desirable in general for
CPE routers to behave like routers on their upstream link,
AND if some ISPs don't want that, it should be a configuration
issue to switch such behaviour on or off. IMHO.
