If you can't get native IPv6 then use a tunneled service like
Hurricane Electric's (HE.NET).  It is qualitatively better than
6to4 as it doesn't require random nodes on the net to be performing
translation services for you which you can't track down the
administrators of.  You can get /48's from HE.

I use HE.NET and have for the last 7 or so years for my home network.
