Insta-feedback audience

(This idea stems from my previous post; temple diodes). TV show rating reportings / statistics are sharpening with the advent of new technology (digital GoogleTV), so these metrics can be better quantified. I think that the audiences capacity to anonymously like/dislike shows will become more apparent thereby reflecting future programming. Imagine in the center of the audience of a talkshow, is a robot (3 times the size of a normal human) sitting there. The face of the bot is programmed to show basic emotions. It would be controlled via viewers in their private homes. Based upon how funny or unfunny the show is, this audience robot, would react. Thus providing an instantaneous indicator of feedback to the show host. I think this idea came from watching Spartacus, where he is forced to fight to the death in a Roman amphitheater because that's what the audience wanted, but when cornered, an audience member wouldn't admit to wanting to see that. So the anon nature of reporting metrics could push pop media into a funny place with this robotic feedback... /random
