You obviously haven't played with IPv6 tunnels in a restrictive environment - like if your ISP doesn't let you host websites. Being able to go to tunnelbroker and get a /48 that you can allocate to all your gizmos and VM at home is magical -- especially when your ISP doesn't want to support IPv6 I gave my weather station its own IPv6 website, with fixed AAAA records, and some dyn dns magic to update tunnelbroker.net whenever my ISP changed my IPv4.
