Well, as you say, we really don't have to overly complicate this wrt.
Youtube IP traffic.

I doubt anybody will argue that eyeballs have traffic to Google/Youtube
traffic. How much?

I remember some flow sample statistics from a few years back here from
Gothenburg, covering some ~10k students with plenty of bandwidth. I
assume these _swedish students_ knew how to use P2P. :)
  Google+Youtube was about 3rd or 4th unique origin AS by bytes
transferred!  I don't have the references available, but this I
personally consider a ~fact for eyeball networks, at least in
Scandinavia.  Prove me wrong. :)
I don't remember what this meant in terms of fraction of the total
traffic, but I suspect somewhere around 5-10%?

If what we want to find out is % IPv6 traffic out of all IP traffic, and
how this might change by some large players, or protocols, (suddenly)
changing behaviour, this is relevant.

I assume the ranking of Google/Youtube has dropped much since then. More
data needed. 

I could write more, but where I want to come basically boils down to
that I strongly suspect that the current IPv6 support infrastructure for
the transition mechanisms today do not support a Google/Youtube ceasing
to use the DNS resolver whitelist method as a connectivity quality
assurance technique.  

And I believe we will have to cope with the transition mechanisms for
quite a while.  We're a long way from native IPv6 to a majority of
Internet users. But OS:s support transition and this is being "rolled
out" every day, everywhere.

So, the operator community should IMO continue to do more to help the
transition.  What would happen if $LARGE_FRACTION of p2p traffic
suddenly moved to v6 transitions? This can happen.

So it is, like you say Marco, not very significant how many % traffic
there is today. There are much more important aspects to look at. I
fully agree with you on this. 

Basically what to follow closely, I think boils down to something like:
  * users type of v6 connectivity, if at all
  * changes to p2p
  * changes to ~top-10 CDN:ish networks (youtube included)
  * rest of the web in general

There are plenty previous work done in following/measuring several of
these points. Would be nice with some potaroo.net type, stable, place to
follow it, though.
