>> Meanwhile Danish ISPs refuse to implement IPv6 because: There's no demand. That completely missing the point and their responsibility in my opinion.

Responsibility to whom?

If there's no significant demand from end-users for something, then we're relying on there being a benefit for access providers.

>> For IPv6 to be successful the ISPs need to role it out, regardless of demand.

>> regardless of profitability

Can anyone give examples of a successful technology roll-out where there was no demand, and no profit to be made?
