ChrisF - Artificial binding of fog to eyespace. John D - OpenGL just doesn't map onto some architectures. OpenGL picked a direction and pushed it. Andy V - might for example not require that OpenGL have a depth buffer, to support tiled architectures. Kurt - emerging theme is that 2.0 shouldn't be fundamentally different, but should leave some stuff behind.
Parallelism is much more prevalent.
ChrisF - stratification is unavoidable. E.g. small screens will care a lot about antialiasing, big screens may not. Subsetting or stratification heuristic will help cover range of platforms. Dale - requiring extensions be shipped and tested before going into spec was a good idea. Jon L - OpenGL user base has changed dramatically even as the API has not.
