While the dumb shader does look fantastic I'm afraid of what will happen when no one has to build another "smart shader".   That would assume we'd always use Superfly.  However, not knowing the render times I don't feel as if it's something that would totally replace Firefly for me.   Maybe for some ultra-realistic renders but if it's going to be much slower I'd prefer Firefly hence the smart shaders would still be useful.   If you could do a comparison render with Superfly dumb shaders and Firefly smart shaders and give us the time difference I'd appreciate it :)
