Not really. The problem with Y2K was the danger of working 
systems stop working/behaving as expected.

The problem with IPv4/IPv6 is about growth. When IPv4 blocks reach the 
exhaustion point, the public Internet can't keep growing... but current 
systems will keep on working.

Doesn't make a lot of sense to me... There's also the possibility of a 
market, instead of the current global (almost free) distribution system. 
And it's not foreseeable anyone will give their addresses back, if some 
money can be *possibly* made from that at any point in future.

Try http://ipv4.potaroo.net instead...

Most really don't as we speak, but there it's not a 0% figure.

Not an issue while IPv4+IPv6 is possible. Vista has this issue solved, 
afaik.

Most of my pessimism comes from looking at the number of ASes in the IPv4 
routing table, and finding only about 3% of them in the global IPv6 
routing table......

Low priority is one thing. Hiding head in the sand is something different.
