Blowing up the DFZ zone wont accelerate the deployement of IPv6, in
opposite, it will make harder to maintain the IPv4 service as well.

The crucial points of the delay of IPv6 deployement are the following

- load balancing at the content provision providers' site;
- home network transition;
- traffic monitoring at the entreprise, where the enterprise management
would like to control and monitor, what is going on.

For the later point the Obama administration defined a deadline of September
2012, if I remember well.

There is a new working group at IETF for home network transition, started
this summer.

Unfortunatly the loadbalancing issues are vendor specifics.

So these issues create delay, unfortunately.

I still missed the arguments why would provide any help in the transition if
PI allocations would be "liberized", just to be pleased for a small set of
PI belivers?

If PI belivers happen to complete their transition as the last ones, in two
yeears -- should we care?

Blowing up the DFZ is a big problem. It should not happen in the near
future.

Thanks,
