This seems so much more powerful than the parametric default shaders of flash (e.g. blurs, convolution matrices). The documentation I've found so far doesn't talk much about accessing the GPU, beyond the higher level OpenGL abstractions. Flash likes to use a separate shader compiler, imitating access to the GPU by shoving instructions through a pipelined (and optionally multi-core) CPU. If you find more info I'd love to see the URL!
