And if you're not working on deploying IPv6 now, will you be able to survive the delay when something critical *does* come online and you need 18 months or whatever to deploy? Heck - we started deploying in Feb 1997 or so, and as I write this, MRTG is reporting that about 5% of our off-campus traffic is via IPv6 - probably due to the fact that we hit Google and Youtube that way. But we *still* have gear and software that doesn't play nice (though almost all of that is our own internal headaches and not very visible to end users - their connectivity works).
