For this exercise, I'm going to assume you have no ARIN space today
(v4 or v6).  If you do, there may be other ways to get space, and
at the very least there may be the question why you're not using
your current space.  I'm also going to assume you want IPv6 space
only, and have no interest in IPv4 space.  We could explore what
both of those do to change things, if you're interested.

This is also my own interpretation of the policy, ARIN staff would
of course be authoritative.

http://www.arin.net/policy/nrpm.html#six58

The policy states you must qualify under the IPv4 policy.  Note,
you do not need to have IPv4 resources, you just have to qualify
under that policy, so we look at:

http://www.arin.net/policy/nrpm.html#four3

You state that you are multi-homed, so 4.3.2.2 applies, a /22
minimum.  4.3.3 also applies, you need 25% immediate need, and 50%
in one year.

Basically you have to demonstrate you will use 256 addresses day
1, and 512 within a year.  That qualifies you for IPv4, which
qualifies you for IPv6.  I don't see anything to prevent you from
combining this across sites, so you need 128 addresses in use at
each site day 1, and 256 at each site in one year.

You now qualify, so back to the IPv6 section
(http://www.arin.net/policy/nrpm.html#six58), you should get a /48
for qualifying under the IPv4 plan.  ARIN should reserve a /44 for
you.

Up to this point the policy is relatively clear to me, and you now
have a single /48, and should be able to assign /56's to both your
sites (or /49's, or whatever you want).  Can you multi-home that
way?  Well, if you have one provider in common and announce the /48
out of both locations to be safe, probably just fine.

Here's the unclear part to me: http://www.arin.net/policy/nrpm.html#six583

In many parts of the polocy we allow a /48 to be allocated to a
"site".  You have two sites in this example, and I think you could
argue 6.5.8.3 could allow you to request a second /48 (which should
come out of your /44 reserve) for the second site.

Now, with regard to fees.  You have either a /47 or a /48, depending
on that last part.  Per http://www.arin.net/billing/fee_schedule.html,
the initial fee should be $1,250, but since you're signing up before
Dec 1 2007 you get the waver which makes that $500.  You will then
pay $100 per year in annual maintenance as an end user.

See, isn't it simple. :)

I will note, you could get your /22 of IPv4 at the same time.  The
justification above gets you there.  The initial fee is $1,250.
The yearly maintenance is per org-id, so for both it's the same
$100.  So, $1,750 + $100 a year gets you both IPv4 and IPv6 resources.

Now that I've broken it down I fully suspect someone will pick my
analysis apart, I'm sure I got something wrong, just hopefully it's not
too major of a detail.
