Have we agreed that in IPv6 we'll use the term "LIR"? We inherited
this from RIPE and APNIC, and accepted it so we could have a
harmonized IPv6 policy, but most IPv4 policies refer to "ISPs."
That's interesting, since "ISP" is not defined in the NRPM, but
"LIR" is (even in the IPv4 section).

So NRPM 6.2.4, would define "the users of the network services that
it [the LIR] provides" as intra-company departments, to whom it
would have to SWIP or equivalent? Is that unusual?

Do we have any teeth to the "return within 1 year" policy? In the
past, the enforcement has been, "or you won't get any more address
space," which isn't much incentive in IPv6.

In what way does the lack of PI assignments inhibit enterprise adoption?
Is multi-homing harder, is it less reliable, or is it fear of commitment
to an ISP?
For large content sites (web hosting providers?), is there any guidance
on how they should assign IPv6 addresses? Should each web server get a
/48, or a /64, or a /128? Or does each server get a /64 (per interface)
and each virtual host gets a /128?

I admit I haven't been following shim6, but would that be one of the
future technology developments that would render this policy
If endpoint and network identifiers are abstracted, then provider
independent space actually muddies the routing table.
At this time, multi-homing in IPv6 isn't fully baked. Does this
proposed policy help?

If most organizations could easily qualify for an LIR allocation, then
how is the lack of this proposed policy hindering adoption?

If most organizations qualify as an LIR, and it's harder to qualify as
an end site, how will this proposal promote adoption?
