The savvy should *already* have some space set aside for that. They
know it is coming. Having this space set aside at the RIR level simply
enables them not setting aside of this space now at the LIR level.
The savvy operators should already be handing new customers at least a
/48 of v6 space for customers in PA space and a smaller chunk of v4 for
use by 6to4 and such transition technologies, or maybe providing 6 to 4
themselves if they are big enough. The links to the customers should be
v6 where possible and with v4 tunneled over v6.
The fact that many operators that consider themselves to be major
operations are still not native v6 is going to make all of this moot, I
am afraid. They are going to hit the wall when runout happens and then
it is going to be a mad scramble with a lot of operators all having
networks in various states of misconfiguration at the same time.
For customers with v4 PI space, they should be assisting those customers
in getting their v6 assignments NOW.

Necessity is the mother of invention according to the old saw. Many
operations work on a "it isn't a problem until it is a problem" basis.
They aren't going to change a thing until they have to. Many (most?)
already have the resources to start in that direction now and not wait
for runout. Building in more cushion simply delays things a bit.
Having the spectre of "no space available" hanging before them might be
enough to spur them to set aside some of their own space NOW and begin

I predict many are going to give out every last bit of their space
judging from the lack of progress so far.

Or new operations just getting started who get a large v6 block and need
a small v4 block in order to talk to the rest of the internet. Where
this *really* puts the damper on things is for a new operator just
getting started and I believe there are a lot of operators out there who
are going to want to hold onto v4 as long as possible after runout so it
serves as a barrier of entry to competition. Imaging trying to start up
a new operation after v4 runout.
