I believe they played with that technology in F1 but were limited by the ability to open and close the valves fast enough. Nissan is currently using a variable lift and duration setup. You can effectively run the motor without a throttle plate. You just drop the lift down to nothing to decrease VE to the point where the engine will idle. Very cool.
