I recently saw that Geoff Houston has measured 0.2% brokeness on v4 (!)
on his site in a test he ran recently:
http://www.potaroo.net/ispcol/2010-12/6to4fail.html  It's there in the
text between Figure 4 and 5.

If for whatever reasons, v6 connectivity meant having access to a
better-functioning Internet than v4, that would put this debate in a
whole new light.. :)  

Cheers,
Martin, crosses his fingers and closes his eyes really hard, wishing
that when he opens them, v6 works better than v4.
