Most likely it's blown out of proportion, in the current global v6
But we know that there could be situations where you risk to lose
(very few, maybe just one) customers, because for them your website
simply doesn't work.
Then it depends what that means to you. If you get one customer
with that problem, and it's a hugely important customer
(i.e. the manager of a company which servers you host),
then it's a risk, I'd say. But everyone needs to make this call himself,
and figure out the likelihood of such a situation.
That was what I meant.

I can understand Geoff, because you risk to end up with a lot of people
using tunnels and not pushing for native v6, because it works
so well, when it actually doesn't work so well.
That tunnels work well, is just an artefact caused by the small
amount of users on v6.
But I disagree with Geoff and agree with you about the fact that tunnels
are _so_ bad,
that you should rather stay on v4 than using a tunnel to get v6.
Just be aware that tunnels have tradeoffs, and don't forget to go native
v6 when it's available.
