Hells bells! This shows just how out of touch I am with it now; I used to be a proficient Flash programmer a couple of years ago, and I gave it up in favour of C++. Looks like I'm going to have to learn it all over again.
It would be awesome to have Flash surpass Java as the premiere browser-based 3D gaming platform. There's a -massive- gap in the market there! (3D Flash MMO anyone?

)
Still looks very primitive though. The "3D engine" still doesn't really look like true 3D, it just looks like what you've always been able to do in Flash which is stitching together images in 3D space. (I know that's not the case, it just seems that way)
EDIT: I take that last paragraph back, looking at more demos, it's actually extremely impressive...

I hate to say it, some of it looks even better than Ogre (i.e. the demos). The latter demo reminds me of the Crysis facial shaders.
Since Adobe has released Alchemy which compiles C++ code into AS3 bytecode to run in Flash, maybe someone will port Ogre to it.
I might consider attempting to port my personal GL 3D engine over (100x simpler than Ogre), then what I learn from that it may very well be possible to port it bit-by-bit. It won't be easy, but who knows.
