Given that most major carriers already have IPv6 running in their
labs and have limited deployments with selected customers, I don't
see why you are so pessimistic. Like it or not, the large ISPs
see IPv6 deployment and IPv4 runout as being intertwined events
and that is why there will not be significant mass deployment
of IPv6 until at least the IANA runout event.

There definitely should be some dialog between smaller ISPs
and their upstreams, not just nagging the poor sales rep who
can only sell what is in the official catalog. IPv6 deployment
is a once in a lifetime network transition that demands special
treatment, and that includes carriers providing a special IPv6
contact point for their customers which are also working on IPv6.

I think that the ARIN community doesn't care one way or the other.
Maybe Podunk is a market that can live with IPv4 long after IPv6
is the standard Internet protocol. We are not all-knowing and cannot
make that determination. Maybe Joe Hotshot college grad will launch
a new ISP in Michigan and wipe out the market share of both Podunk
ISP and PaBell.

And opening a gap in the market for Joe Hotshot. Not to mention
antitrust lawsuits.

A fee on IPv4 usage is a component of the connectivity rate and 
I doubt that anyone can avoid a restraint of trade lawsuit this way.
