The impression I got was that you could vary the length of the lifter continuously to basically modify the cam's profile. Looks like they just have VVT via timing chain phasers though.
Koenigsegg owner is developing a camless motor that uses electronic lifters. It's pretty awesome, can press a button to change the tune and run variable cam profiles, etc.

Yea that's different. It's basically just a solenoid actuated valve. Tough to do on a car because it takes plenty of electrical power.
We've been having solenoid driven injectors on diesels and that alone is difficult to manage because of the power requirements. The valves work the same way (you're just pushing a valve stem instead of pulling a poppet), but it takes even more power than the injector drivers because of the forces involved and the amount of valves. It requires really big ECMs and lots of electricity.
