Variable cam timing

[jfaubion]

     Ok so if we use a clutch or coupler to allow it to slip this would 
     provide a way to retard the cam but how do we then make up the 
     difference again??

Based upon Ed's explanation, it seems to me that what is needed is a 
magnetic coupler or clutch on both the crank and and cam(s).  Under computer 
control, you could allow the cam or the crank to slip momentarily thus 
changing the phase of the cam.  With a DOHC, you could completely adjust the 
phase of both the intake and exhaust.  
     
Just an observation from a dumb EE.
