This is precisely why someone else on the list suggested that the
content provider should run their own 6to4 relay and anounce 2002::/16
to their IPv6 peers. That way, the IPv6 packets take the direct IPv6
route to the content provider, and the IPv4 path is just a stub in the
content provider's network. Admittedly, if the IPv6 path itself has
issues due to poor peering, poor bandwidth, neglected routing, that will
rear its ugly head.

What about these two?

Have you tried both of these yourself?
