This is definitely an  interesting way of ensuring players are solving their own long term problem as well as short term, which can generally be seen as good for the community as well IMO.

The one challenge you will face to this proposal is that not all products and services are created equal.  As an ISP in Canada that sells Wireless and Wireline solutions to all markets (Business, Consumer, Partner) we have seen that each case has a different propensity for IPv6 adoption, and certainly a broad mix in whether IPv6 solves the IPv4 depletion problem.  

For instance, a Consumer Wireless service is fairly predictable in its requirements for connectivity, which means it could be serviced with an IPv6 only connection, with NAT64/DNS64 and 464XLAT for instance.  The same cannot be said of an Enterprise client's Internet and WAN services.  They will run dual-stack undoubtedly for a long time. In terms more generally applicable at Google, I imagine the same could be said of cloud services across Business and Consumer markets.

My point is simply that drivers and implications are different across these markets.  In general, I would agree that we all want to see IPv6 adoption across the board regardless of its efficacy to solve the problem of IPv4 address depletion.  Just want to throw these thoughts to the community for consideration of policies to the effect Jason has proposed.
