Yes.  My impression is that the idea in Daniel's draft is that the ISP
will take the load of most DNS queries, and will effectively mark a
boundary of split-horizon, so that some names resolve both outside and
inside the local network, and some will resolve only inside.  This is
really a formalization of the way many CPE systems already work, where
they update services like Dyn (full disclosure: my employer), no-ip,
and so on.  The differences seem to be (1) that the relationship is
somehow stapled to the ISP rather than to an outside service and (2)
that the commands all flow over Dynamic Update as opposed to any other
protocol.  Personally, I see the value in (2), but I'm worried about
(1).  Thinking as a vendor, I note that (2) basically means ditching a
lot of running code, although for a protocol I think is poorly
designed.
