Yes I am saying a household that mulithomes is abnormal and with
today's and contracted monopolies I expect that to continue.  You are
not a normal household in that 1) you multihome 2) you are willing to
pay $1500+ US a year for your own AS, IP assignments 3) Internet
service, much like cell phone service is a commodity product and many
people go for the lowest price.  They are not looking for the best

If they are using RA's to assign their network and the router goes
down they can loose the network as well as the router thus going to
link-local addresses.  This has been discusses ad-nauseum on this
list.  As I recall you played a big part of that discussion and it was
very interesting and informative.

I hope this happens but I'm guessing that with marketing and sales in
the mix it will be another up charge to get this "service" and enough
people won't pay it that we will be fighting these problems for a long
time.  Some businesses will pay it and some won't but the home user
will probably not.

These are businesses were talking about.  They are not going to "give"
anything away.

Debatable but not worth an argument.  Having said that the ability to
1) not have to renumber internal address space on changing ISPs 2) not
having to give a printer (or other device with no security) a public
IP address or run multiple addressing schemes and the security
implications there of  3) change the internals of my network without
worrying about the world are all important and critical issues for me.

I realize that these arguments are at layers 8 & 9 of the OSI model
(politics and religion) but that does not make them less real nor less
important.  They are not the same issues that ISP operators may
normally have to deal with but they are crucial to business operators.
 The DSCP/RA arguments are of the same criticality and importance.
