I too have heard of some work that Honda and Jag are doing in that area. I can see very easily how selenoids would work. But I don't see any way that a solid single cam with fixed lobes for both intake and exhaust valves could be made to work. That's not saying that it can't.... I just don't see how it could. But I sure would like to have a ability to change perameters through the PCM. That would really be cool.
