I am willing to help. I would need to see the details as to what kinds of participation are available. If you could send me a link or drop me an E-mail I can see what I can do. As mentioned before, I currently do not have a substantial home setup at the moment. I am in the middle of a move and it will be a few months before I can settle in.
Additionally, What is the priority for developing a full IPv6 feature set? Is it anywhere on the road map?
