Yeah, dan is decently radical. :)
I think the voluntaryst anti-IP stance is intriguing. You have a community that, on the one hand, upholds personal property rights as inalienable. But on the other hand, they demand that intellectual property, if public, must be commonly-owned (of course, trade secrets are fine - but everybody agrees on that one). I see how both of these are logical conclusions of the non-violence principle, but they also look (from the outside) to be a bit at odds with one another. This is neither the time nor the place to discuss it, I suppose. I'll write a blog about it one day.
