IPv6 Site-Local Addresses, the analog of RFC 1918, were deprecated because 
ambiguous addresses were considered technically flawed.  The IPv6 WG has 
proposed Unique Local Addresses which use a 40-bit random field in the 
prefix to reduce or eliminate (depending on the class) the chance of 

ULAs are intended to be used for internal-only communication (possibly 
layered on top of PA addresses), private connections between companies, and 
any other purpose that needs uniqueness but not global routability.  While 
ULAs appear to have consensus, a few vocal objectors wanted to see if the 
RIRs would change their policies to provide PI space for these needs before 
letting us proceed with ULAs.

OTOH, it's been asserted by many folks, including myself, that even 
end-sites that wish to deploy IPv6 will not do so if they are locked into 
provider-based addresses for their internal communications.

Multihoming in particular is not feasible with the existing scheme, and some 
believe that this will lead to organizations using ULAs internally and 
NATing at their borders into PA space.  Since NAT is generally considered 
evil and was supposed to be unnecessary in IPv6, the only solution is to 
create allow IPv6 PI assignments.

I'll note that this proposal was solicited by an active AC member, and 
several other ARIN-related folks seem to agree -- at least until the Multi6 
WG comes up with something better (years if not decades away).

Argh.  These kinds of things really need to be kept current.

Okay, that's what I'd have expected anyways.

Glad to hear it.

$1,250/yr since the expected assignment would be /48 for nearly all sites.

Still, that's a fair chunk of change if one doesn't need global routability, 
particularly compared to (free) ULA space.  I do think it's reasonable to 
people upgrading from PA space; it's a drop in the bucket compared to being 
multihomed in the first place.
