That's ARIN.  Things are different in RIPE areas, where ISPs are
forbidden to charge per-IP but may tie routed subnets into a class of
product instead.  IPs are subject to justification, yada yada.

IME with RIPE-area ISP practice: the bare minimum is a /64 which, under
the "normal" address partitioning used in IPv6 is a single routed subnet
containing 2**64 addresses.  Think of a /64 as the unit of assignment.
A /127 is only used for point-to-point links.

While in theory you can divide the subnet boundary area, in practice so
many things assume /64 for a single subnet, including various of the
automatic address assignment schemes, that you're not going to sensibly
get away from a /64 being a single local link network.

Next up is:
RFC 3177 IAB/IESG Recommendations on IPv6 Address Allocations to Sites
which basically says "assign a /48 to every customer", giving each
customer 2**16 networks.

Some ISPs in RIPE-area, in my experience, do this.  Others do not.  /60
might be reasonable for a home-user.  /48 for business users.  These are
standard assignments and you shouldn't expect to pay more for them.
There's a general feeling that a basic plan should still include more
than a single /64, opinions vary though.  Myself, I think this is
because otherwise you're forcing home users onto a flat network and ...
well, forcing a flat network on someone might come back to bite you if
they claim later that they only did so because you forced them into it.
Addresses aren't expensive, lawsuits are, so let them use multiple
networks if need be.

Within ARIN, there's a declining partial waver on fees for IPv6
addresses:
  http://www.arin.net/announcements/2007/20071004.html
and I have no first-hand knowledge of pricing of IPv6 in ARIN zones, so
can't help further there.

Moving out of my area of knowledge, but I believe that you can only get
routable IPv6 address assignments if you have an AS number, even in
ARIN.  Not sure.  In RIPE, you can only get portable address assignments
if you're an LIR, otherwise you get space from the ISP and have to
renumber.

The same general pressure is that there should be fewer entries in the
global routing table for IPv6; whether that's viable or not in reality,
I don't know.

Note that renumbering in IPv6 is supposedly significantly easier than in
IPv4, in part because the route advertisements can include multiple
prefices and the nodes should configure themselves up on all networks at
the same time, so you can have an orderly migration.

In practice, my colo box has static address configuration so I'll need
to do things manually, but should still be able to have both old and new
addresses at the same time as a supported protocol feature rather than a
hack to get multiple networks on the same link.  I'll be able to give
more feedback sometime early in 2009 after the netwerkvereniging which
I'm a member of becomes an LIR and gets its own IPv6 address space and I
have to renumber.  Yay.  Renumbering.  My heart overflows with joy at
the prospect.  Or something.  Well, we'll see.

Pass.
