Marco Hogewoning of Dutch ISP XS4ALL talks about the roll out of IPv6 in their 300,000 customer network. German modem vendor AVM supplies them with a CPE that supports native IPv6, although it does have some limitations that need to be ironed out. Marco talks about how they got in touch with them, how they handle the spec and the issues, and how the project gained traction when the Sales department got interested.
