In reply to jared mauch.

Jared, you're exactly right that all it takes is one critical feature, one link in the chain, that isn't supported on IPv6 as it is on IPv4 to get in the way of deployment. I've been working with the team here to understand what the latest is on the specific issue you have pointed out here and hope to have some good news for you very soon (and posted here as a comment for everyone else as well).
