This is what multiple manufactures are doing.

I think the best, simplest and most elegant supercharger solution that was already mentioned is the electronically-controlled, variable-geometry pulley, which can essentially create a small-pulley high-boost-map for more power down low, and it can taper off boost by creating a large-pulley low-boost-map for less power up high. This means the supercharger never has to over-spin or bleed boost.

I'm speaking of what we as consumers can do to improve our EXISTING FI systems. With what I am describing, there are no electronics, no electrical connections and no batteries involved. It's purely mechanical. This would be something a home mechanic would be able to piece together with existing parts that are already out on the market.
You're talking about something that would have to be mass-produced by a vehicle manufacturer that adds electric motors, additional batteries and a redesigned charging system. Why turn mechanical energy into electrical energy just to turn it back to mechanical energy, when the first two steps can be eliminated?
The first video you posted above is addressing turbo lag, I'm addressing supercharger parasitic load of an already existing and installed supercharger unit which eliminates the lag in the first place.
The second video seems to be focusing mostly on fuel efficiency and regenerative electrical production, I'm addressing performance by freeing up the power and torque at high RPM's which would normally be needed of your engine by the supercharger and that you are already producing anyways, to make it available to the drive train instead. (Besides, would you really ever want anything designed by Chrysler/Fiat to be bolted up to your engine?)
