Electronic valves

Hi

BMW? developed a system using piezo-electric stacks about 10-15 years ago. 
There was an article in Road &Track about it... but I don't have it. 

More recently (about a year ago) Turbo magazine had an article about 
solenoid operated valves.  They were operated by electronics from 
Electromotive.  I think I still have the magazine.  When I find it, I'll 
give you the date and manufacturer of the head.  I also don't remember the 
engine under the test.

I've heard rumours that a company somewhere had developed a system 
that replaces camshafts with computer controlled solenoids to actuate the 
valve train. Has anyone here heard the same, or know a logical point to 
start searching from?
