What's impressive (IMHO) about Trackdaze is not the liberalization of on-track action, but their recent (2012) focus on specialized training (race craft), and the fact that they offer coaching at their events.
I agree with Kurt that the line between DE and racing is an important one, and people should decide which side they want to be on. Personally, I think everyone should be racing, if for no other reason than to share the costs.
