Well here's the thing about allocations.  All an IP allocation is, is a entry
in a data base saying an ORG has a right (from an RIR perspective) to use use
an address range.

Now a AS can actually use any IP space it wants internally, and if it gets
another AS to accept their routes for that IP space and that AS's peers agree
to accept those routes, the first AS can actually use that IP space.  The RIR
or IANA has zero legal authority to stop this as it's just a bunch of private
networks agreeing on some one using IP space.

Now this gets a lot more fun as we get closer to true IPv4 exhaustion.  If
there is a business case between two or more providers to side step a RIR
process and recognize IP allocations that the RIR does not, who really has the
power to stop them?

Think about this, if you're a service provider in the US, and the big US
networks agree to route your IP space that is actually registered to some
network in Kazakhstan according to the RIR's, what will happen?  from the
service providers perspective the average user will have access to 99% of the
US networks (which is really all people want :) and most likely half way
decent connectivity to other AS's.  Sure, this sucks, but 99% of the people
don't care, and still provides better connectivity to services people want
than IPv6 does.

So follow the money and see how IPv4 exhaustion plays out ;)
