    As is probably obvious from the sidebar, I'm pretty enthusiastic about IPv6 - for quite a few reasons, not least of which is implementing a new Layer 3 protocol after guys like Vint Cerf already did most of the cool stuff. However, I didn't want to simply complete this task - most people complete all of these tasks …
