I know this is pretty irrelevant to fuel economy and ecomodding, but what personally gets me excited about this is the fact that it would work really really well at motorcycle engine speeds.
The Honda F20C had VTEC and 9000rpm, but no other manufacturer has dared to use a heavy switchable rocker or bucket at that speed. Porsche 911 GT3s and the Lexus LFA use fixed cam profiles, Ferrari has their continuously variable profile (which probably has issues with uneven lobe wear) that moves the camshaft around. Some BMW bikes have 2 cam profiles and switch by sliding between them as well, but that system needs I think 1 actuator per 2 cylinders to slide the camshafts while they're not in use, which is annoying.
This is much simpler. No cams moving around, ability to bleed off almost all the VE while also having great low end torque, no reciprocating mass to add stress to the valves, and little friction.
On a motorcycle, you could throw away the ITBs for this, and eliminate all the emissions and fuel economy problems. High revving car engines become much more practical, since you get great torque everywhere, and can use less valve spring pressure.
