The demand for IPv4 is incredible right now. The value of a /8 went from $0 to close to a billion dollars.
The claim that new IPv4 space has no value is ridiculous. These ranges don't have to be perfect.
I think IPv6 folks just don't understand how high the demand for IPv4 is, it's gone UP since IPv6 came out and folks have realized IPv6 is going to be much much harder to adopt then expected. And this proposal does nothing to stop IPv6. You know your IPv6 proposal is bad when it depends on stopping others from improving alternatives :)
