>OTOH, it's ridiculously easy to get PIv4 space today (512 hosts and two pipes or tunnels), and there's not all that many companies doing it.  It's not growing much either.  The doors are already wide open for a land rush and nobody is taking ARIN up on

This is perhaps the most pertinent question to have been asked during this thread and I'm not sure I saw any answer to it. So I'll ask it again. What is the evidence that using v4's PI policy for v6 would lead to a land rush of catastrophic proportions 
and the routing table becoming huge? All I've seen so far is hand-waving doomsayers.

Remember that to get PI space at all you have to know what you are doing, and you have to justify the usage. And the process takes a certain time. All of these would tend to discourage the casual enquirer.
