I'll add to Dan's statement by saying Toyota developed a DMD for the Supra I6 to quell destructive vibrations. Seems the engines were failing on the test stations with only a normal damper.
I'll see if I can find the link to a website with info about it. They even showed graphs (from 3k - 6k IIRC) of how much destructive vibrations (I.E. crank whip) a DMD reduced vs just a normal damper.
