How many hours of work... Seems like quite a few to me.. So unless you get lucky and someone writes it up for their own use and shares it. You have to provide enough incentive for someone to do all the work. $100 at best at best cover an hour worth of work - this is clearly more than 1 hour to implement, etc.

@jwt Definetly looking forward to it and be glad to test it out in first snapshots/betas that will have it. We can easily hook up an v6 only network in the lab (there should already be one) and give it a spin :)
