To me the most important thing about IPv6 is how it enables reliable peer to peer networks. IPv4 is the bane of existence to p2p networks since you have to so much extra shit to make it work (Public address discovery, NAT hole punching, relaying connections through some machine with an open port).
With IPv6 you can just stick your address on a DHT and peers can connect to you 100% of the time, no matter what.
The only thing that sucks is that you can't count on an internet-connceted device having IPv6 yet.
