The idea behind the split of the draft was that, at the host-router interface, 
it does not matter whether/in what way DAD is performed, so 6LoWPAN hosts will 
be interoperable with any way we do this.

Now, within the "fabric" (set of 6LoWPAN routers and possibly edge routers), 
the interoperability becomes more interesting.
In particular it would be useful to enable routers with minimal memory 
requirements to work together with larger routers that provide additional 
services.  (That was also the idea between the router/ER dichotomy, but it 
seems we need a more flexible assignment of functions.)  It would be nice if 
all the alternative ways of running the fabric I mentioned in my split proposal 
wouldn't lead to different, non-interoperable protocols.  I think that can be 
done, but a design with many options is significantly more complex than one 
that can be limited to a single model.  Fortunately, this complexity is limited 
to the routers/ERs; hosts don't have to care.
