Agreed, with one proviso: it is reasonable here to identify the present
lack of scalable site multihoming as an obstacle to deployment,
and to suggest ways in which this obstacle may be met and
dealt with.

Our job is twofold: firstly, try to arrive at consensus over a
good approach to scalable site multihoming that includes
the current & former network operators participating in the WG,
and secondly, to take advantage of the availability of
willing operational experience and clue to avoid some of
the brick walls we have hit (or approached at high speed) with IPv4,
like this unpleasant period in late 1995:

groups?selm=DHqupL.ALC%40gpu.utcc.utoronto.ca&oe=UTF-8&output=gplain

Admittedly we learned quite a bit about how to build and operate
fast routers from this sort of thing, but hitting the wall
operationally is far more costly today than it was when
the Internet was much smaller.  I believe the market
as a whole will choose to avoid serious scalability problems
that are already known, since there are more than enough
that are not known yet.

Whether this happens by engineering IPv6 in directions different
from -- but informed by -- IPv4, or by non-deployment, possibly will be
influenced somewhat by  cooperation here and between
multi6 and the Internet Area.
