Fernando & Douglas,
Just to focus on the point whether enabling IPv6 is good or not... which is I think the major disagreement that I have with Fernando's points.
I would hate to do 'rogue access points' again but with IPv6. IPv6 is there, whether we like it or not, at the very heart of enterprises data centers thanks to Windows 2008 (there any IPS in the DC will not detect IPv6 attacks between Windows server -- assuming that one has been compromised)
Security people saying 'NO' are looking for trouble, they should say 'YES, BUT' :-)
My point is that indeed organizations should move to IPv6 but this must be planned with training, education, ... then deploying at least IPv6-aware IPS/Netflow/IPFIX/... and buying network devices that could deploy safely IPv6 (including layer-2 mitigation). CISO cannot be blinded.
Then, there are pretty good business reasons to deploy IPv6 in the coming months.
Or did I misread your point?
