Woah. I don't think we've had vector quantization in a mainstream codec since Cinepak! This would be a radically different and more complex implementation, of course. Cinepak had to decode 320x240 15 fps on 75 MHz processors without SIMD.

These are some pretty different ideas. I look forward to seeing if they can make practical implementations of them.
