In order to address these points, and to get out of the way of the work
you are doing, I wrote up a draft that discusses the DAD implications of mutli
addressing. Please have a look and send  comments.

        Title           : Delegating a Prefix to a Host for Multi-addressing Purposes
        Author          : Fred L. Templin
	Filename        : draft-templin-v6ops-pdhost-00.txt
	Pages           : 6
	Date            : 2015-11-05

Abstract:
   IPv6 prefixes are typically delegated to requesting routers which
   then use them to number their downstream-attached links and networks.
   The requesting router then acts as a router between the downstream-
   attached hosts and the upstream provider network.  The router could
   also act as a host under the weak end system model, and otherwise
   behaves as a standard router.  This document considers the case when
   the "requesting router" is actually a host, and receives a prefix
   that it can use for multi-addressing purposes.  The host does not
   connect any downstream-attached networks, and uses the prefix solely
   for its own multi-addressing purposes.
