I dunno.

 From their site "In 2000, we drove one of our Camless vehicles to  
the top of Pikes Peak. In the same year, we took a Camless vehicle on  
a 10,000 mile U.S. tour. We have operated vehicles from a Camless VW  
Jetta to a Camless International semi-truck and have run our systems  
up to 15,000 rpm frequency."

I don't disagree, but it would appear they do have working vehicles  
built, if only proprietary systems, it's a start at least.

Well, if anybody else has a 4g63t engine they'd like to do it with,  
that'd make 2 of us... I would like very much to see DSMLink  
incorporate control over valve timing the way the fuel and spark is  
controlled... see the charts here:
