There are still a number of hurdles to overcome. My new web/application server will be IPv6 capable. I asked a number of large dedicated server providers in the US if they could provide me with an IPv6 capable dedicated server. Some simply didn't understand my question. Others replied that the server was of course ready for IPv6, only their network wasn't... I couldn't find one decent solution and I am therefore now preparing a colo box which will go life in about one month in a data center which was until recently used by Google.
And that is only the server side. Most ISPs don't have the infrastructure to carry IPv6 traffic from their backbone to the home users. Many DSL networks are simply IPv4 and can't be upgraded easily. The better ISPs provide some sort of IPv6 tunneling over IPv4 but you need to be a real nerd to get it installed and working. Documentation is almost absent, and knowledge at helpdesks about IPv6 is zero.
