It's a fairly ugly way to deliver IPv6, but, as transition technologies
go, it's the least dead-end of the options.

It at least provides essentially native dual stack environment. The
only difference is that your IPv6 access is via a tunnel. You'll probably
be limited to a /56 or less over 6rd, unfortunately, but, because of the
awful way 6rd consumes addresses, handing out /48s would be
utterly impractical. Free.fr stuck their customers with /60s, which is
hopefully a very temporary situation.

You should definitely push your providers to give you a /48 if
possible. If /56 or worse /60 or worst of all, /64 become widespread
trends, it may significantly impact, delay, or even prevent innovations
in the end-user networking/consumer electronics markets.
