I'm currently on the end of a 6to4 tunnel and I've configured my Linux
box to prefer tunnelled IPv6 over native IPv4, and I'm in the asia
pacific. I've had no issues what so ever with the youtube content being
delivered over IPv6, including 1080p videos. 

Here's quite a spectacular 1080p video to test with.
