You guys are forgetting about (or choosing to ignore) Shockwave3D, which is a very usable Web3D platform with a large installed base (way, way bigger than Unity, but not as big as Flash). Adobe has announced full AS3 and Flash 10/Flex support, meaning that you can wrap Flash movies inside 3D environments inside Shockwave3D. Texture your Flex app onto the tree trunk in your enchanted forest, that sort of thing. The pipeline from 3ds Max is relatively bullet-proof too, but support for other authoring environments is a bit spotty. But compared to our favorite Flash based 3D platforms, Shockwave3D is a breeze to get models and animations into. of course there's the minor matter of having to wrap your head around Lingo, but it's not so bad once you get used to it. Just food for thought.
