Youtube over IPv6 for non-whitelist users?

It would be nice if there was a way to see if the content was streamed over IPv6.  Perhaps in the playback diagnostics feature available when right-clicking on the video.

We haven't yet formalized any policies.  Until then, they could
probably tell by seeing if videos are served over v6 or not.

Again, this transition from whitelisting to blacklisting is new, and
just the next step toward universal AAAAs, which is the ultimate goal.
