Have you looked at primivol? Didn't you ask about the demo? 1,6, 7 have definitely been talked about and I understand are planned in that direction. Hopefully existing D|S plugin devs can get the sdk and start trying to port plugins. I don't see that kind of sound dev, at least not for awhile. Maybe some mixing, but there are areas that need some improving that are more in carrara's true area. Like better shader management and some improvements in animation tools.

No need to think outside the box....
