I seem to remember a project to give free porn in order to get people to use it? the site was www.ipv6experiment.com but it is now offline, so here is a archive copy of it (no adult content)
IPV6, it is the future, just not any time soon for mass deployment... Unlike IPv4 where you can figure out the basic network in your head, IPv6 is just so much more complicated for basic things... not saying impossible, just a lot harder than IPv4.
Anyway, back to the topic, apart from the above, I am not really sure there are many interesting uses of IPv6 over anything that can be done on IPv4... in theory it means every object you own can have a public ip address (kettle, oven, fridge and more!) but until there is a real practical reason to do so, there is not really much point... and again, this can be achieved in IPv4, there just isn't really enough for everyone.
