Exactly.   I think that the wish for an expedient solution often ignores the 
fact that a step-by-step implementation of the real solution isn't as hard as 
the proponents of expedient solutions often fear.

Regarding the question of whether to update the primary on the CPE device or 
update the primary on the ISP, the main motivation in my mind for doing it on 
the CPE device is that it avoids a massive key management problem.   If the CPE 
device is primary and the ISP device is secondary, the ISP can publish a SIG(0) 
key in a well-known zone and use that to authenticate zone transfers.   Going 
the other direction requires the ISP to have a public key somewhere for every 
single customer.   There's nothing fundamentally hard about this, but I think 
the other way is easier.

Having said that, of course we should describe how to do it both ways.   I just 
think the CPE being primary is going to be more popular, assuming both 
solutions are equally well-supported.
