Pat, nice job linking to the Internet Society's "Deploy 360" website. There really is a wealth of information there concerning IPv6 and DNSSec.
http://www.internetsociety.org/deploy360/ipv6/As you mentioned, I think it's safe to say that we're going to see IPv4 and IPv6 coexist side-by-side for quite some time. Once IPv6 "goes live" I am sure that several security concerns will arise (and be remedied), but unlike IPv4, security was taken into consideration from the ground up in IPv6's development. One consideration with IPv6 that should be taken into account is that it will increase the importance of DNS (which is already critical). If DNS isn't working properly, it's no big deal to type '192.168.10.20' but can you imagine typing '2001:470:1f10:deb::2'? Even with the IPv6 address abbreviation it would still be a pain.
With IPv6 coming up, 64-bit computing replacing 32-bit, and storage space getting cheaper and cheaper, the days are bright for information technology, and I for one am excited about the future.
