I just published the Demonstrating DHCPv6 extension for the IPv6 Test Lab in the TechNet Wiki.
This extension reconfigures DC1, the native IPv6 router for the Corpnet and Corpnet2 subnets, to stop advertising address prefixes and act as a DHCPv6 server. Additionally, you configure DC1 with a DHCPv6 option for the IPv6 address of a DNS server.
If you have an idea for an extension that adds something new and interesting to a test lab, by all means, write it up and publish it in the TechNet Wiki. Here is a blog post to get you started.
