I read draft-thubert-6man-ipv6-over-wireless-00. I quite like the
description of the issues with wireless media.

There is however one thing I miss: The abstract says "This document describes
how the original IPv6 Neighbor Discovery and Wireless ND (WiND) can be applied
on various abstractions of wireless media."

I'm also interested in *why* WiND should be applied. In particular, Figure 2
shows a complex multi-layered setup.

So my question is, why not use routing and keep subnets restricted to one
link?

I hope there is a clear set of arguments why routing is not sufficient. 
Right now it reads too much like a primitive routing protocol on top of ND.

Another issue that often shows up with registration based systems (such as
quite common with IPv4 and wireless) is what happens if a host has more
addresses than supported by the registration system?

I.e., it might scale better to have lots of point-to-point links and prefix
delegation than to have a single big subnet and a hierarchical registration
system.
