So start out by using site-local IPv6 addresses and get some routable
addresses from a tunnel broker site like the one at Hurricane Electric
Then when you get a local connection from your ISP you can simply
renumber. And don't try to complain about the pain of renumbering because
I won't accept that argument. In fact I *WANT* you to suffer that pain if
there is any. That's how you will learn how easy (or hard) it is to
renumber using IPv6.

You don't need permanent space. IPv6 is not IPv4 with more bits.

Any IPv6 connection to the IPv6 Internet will let you operate in learning
mode. Whether it is a 6bone connection or a native local connection is

200 households is not very much for an ISP to hook up. One single
household connection takes up a /48. Remember that IPv6 is not just IPv4
with more bits. Any site that will have two or more IPv6 devices is a
network and therefore that site will use a /48. Forget the IPv4 practice
of counting the number of devices on a subnet and rounding up to the
nearest power of 2. That is obsolete with v6.

Why do you need "portable" space. In fact, please define what "portable"
space is because I don't understand. Assuming that you are using DNS, if
you switch IPv6 providers just add your new providers addresses to your
network and to your DNS. When you switch off the old provider then just
remove their addresses an run only with the new ones. Don't try to tell me
that this won't work because you don't know that because you haven't tried
to do it yet. The only way that we know this doesn't work with v4 is
because people *DID* try it and they learned through experience. If you
want to learn v6 properly then you have to set up the experiences and then
live through them. After a year you will be a grizzled veteran and will
truly understand what v6 can and cannot do.
>I don't even need a /48 for all that I expect to be doing. That's just
Bah! A /48 is puny. I would use one of those for my aunt Mabel's house and
another one for my granny's. Who cares if I'm wasting 99.78% of the
addresses in each /48? It's simply not relevant because there are lots
more /48's where those ones came from.

There are some subtle nuances to the term "multihoming" that many people
are not aware of. IPv6 has always supported multihoming in the sense that
a device interface can have many addresses at the same time to communicate
on the physical link, within the site, within the organizational boundary
and with the world through one or more upstream network providers. But
this is not done with BGP multihoming. To understand it better you really
should try it out and experience it for yourself.
There just aren't enough IPv6 experts in existence to produce the kind of
documentation and training tips that we are used to in the v4 world. At
this point in time you need to grit your teeth, accept that you are a
pioneer, and forge ahead no matter what the obstacles are. Since there are
no complete maps of the territory, you need to keep your eyes open,
explore the v6 possibilities and maybe you will become a future fount of
wisdom on IPv6.
