Robin,
I am adamant that end-users need portability and portability based
multihoming, not some supposedly easy renumbering process and
multihoming which automagically renumbers their network.
I think that we strongly need to distinguish between addresses used
as locators and addresses used as identifiers. Users will probably
want to keep the same identifier, but they don't care about the locators.
Today, most end users received their IP address (which serves as
both locator and identifier) through DHCP. They don't need to keep
the same IP address always and some ISPs that are charging premium
for 'static' IP addresses make sure that DHCP assigned addresses
change every few days. End users who are willing to have stable
"identifiers" today rely on the DNS, either by coupling the DNS
server with the DHCP server or by using services such as dyndns.
Endusers don't care about portability of addresses, most of the
time, they don't see the IP addresses.
