Sorry Matt, I think you're missing the point.
You're already relying on a computer to interpret colour, intensity, focus and everything else for you. There's no difference in instructing the sensor to record the image with a red, green, blue or pink cast to what you're already doing when you tell it what colour temperature to record. Try switching to B&W - same thing! In the same way you can tell it to record 2, 4 or as many stops of grad as you like merely by adjusting the ISO rating across the sensor.
It's all pretty simple really and the only reason I can think of for why they haven't done it already is because it would kill filter sales and, perhaps the processors just aren't fast enough yet to cope, but it will happen - and sooner than you might think.
