By adding valve position sensors, you get full
servo-valves.

This allows modulation of lift, timing, and duration.
Eliminates need for a throttle, just open the valves
the required amount.

One can imagine multiple valve opening events during a
single cycle, perhaps for swirl control or stratified
charge management.

Been waiting for them to do this for years, ever since
I worked on old time disk drives with voice coil
actuators for the read/write heads. The cost was high,
but the technical ability to position that kind of
mass quickly and accurately existed. 

So of course, the first thing I thought of was
actuating the valves on my racecar.
