Hmmm, let me rephrase.

That technology is already commercially available. Heck, a camless prototype engine was already compeleted by BMW years ago utilizing electronic valve control.

Though the current problem is the cost of implementing this vis-a-vis the very reliable (and relatively cheap) camshaft technology that is currenly propelling all of our vehicles. As I've said, the variable valve timing technology is sort of a middle-ground between the two technologies.
