[ppml] 2005-1 or its logical successor

[Christopher Morrow]

some below, and jumping in to bill's actual message since I missed the
original. Keep in mind that I personally think that the 'classfulness'
being imposed on ipv6 seems bad... It's convenient, but it's just
wasteful.

I think the 'metro area' part was more an effort to say: "It's ok to
have 1 assignment of $size to each place you want to light a
connection, but we don't really want to support folks just asking for
PI 'because'." So making a metro, or location dependent proposition
seemed reasonable. (for folks with disparate locations and no backside
network connecting them all together)

the reasoning behind this (forgive me if someone else already said
this) is: "Multihoming is a business decision, not a size decision".
Basically, there are lots of new regulations coming around that will
'require' mutlihoming (provider redundancy sorts of things for end
sites) that have nothing to do with the size of the organization under
the thumb of the regulation.

You may legittimately have a single front-end e-commerce site that
supports millions of dollars of revenue, operating off say a very
small number if host addresses (www.google.com comes to mind
actually). Forcing the multihoming to have some arbitrary number of
ips in use seems counter productive. It's not the metric of interest
for this problem.

Also, there should be much more work done on other methods of
multihoming. Methods that make it simpler, and less globally intensive
for everyone in the long term. So, there may be flavors of multihoming
in the future that require PI and flavors that do not (and provide the
flexibility to switch providers at will with little penalty to the end
site).

My major issue with the 2005-1 proposal was it's 100k host count
requirement, it just seemed like the wrong way to measure for this.
