however the flip side of this is an enforced shortage of IPv4 because of its consumption will also force people to actually act on getting onto IPv6
Proof needed. From what I see there is no shortage of IPv4. I know RIR are short (or done for some) on IPv4 but considering the amount available on market, there are plenty of IPv4 available. Emptying the free pool of RIPE won't help IPv6, it will only exclude future and small players of this double-stack Internet. Speaking of IPv6, many prefer to invest in CGN or any technology expanding the life of IPv4 than deploying the current Internet Protocol (and when you buy a box to do CGN you don't have money to replace that older gears that doesn't support IPv6). 20 years wasn't enough to deploy, how a handful month could be ?
