If there was a way we could make it all run out at the same time for
everyone that would definitely be the fairest situation possible.

Unfortunately, that's not how it's going to happen.  All you really
can do here is juggle things around at the RIR so that when the day
comes that they run out, they run out evenly for ALL sizes of requests -
not that they run out of, say /12-sized blocks but still have plenty
of /21 sized blocks left.  In short, you can make it fair for all of
the requests in the pipeline at the RIR to all fail at the same time.

But in the world it definitely won't be fair.  The orgs that come out
ahead are the orgs who have inefficient utilization of assigned blocks
and are able to retrieve those from customers.  For example someone
alleged on the list a few months ago that one of the cable ISP's was
handing out /29's via PPP to CPE NAT/routers - all perfectly legitimate
under the rules - but with a few tweaks in their router and now all 
their customers are getting a /32 the next time their
CPE disconnects and reconnects and the cable ISP has instantly
generated many 5 times more IPv4 than they had.

Assuming that every ISP out there has been hedging somewhat along these
lines, the advantage will go to the ISPs who have large amounts of IPv4
already allocated to themselves.
