GM's DoD and DCX's MDS are a little different I belive. I think that MDS doesnt colapse the lifter, just shuts off a bank of injectors. DoD shuts down both.
Not to mention the engine design for the hemi.
Hemi my ass....

Nope, they do the same thing, both lock the lifters off the cam lobe AND shut down the fuel. There are a few things I still don't understand about DOD but I'm getting my answeres slowely enough through a couple sources. I'll have all my questions answered mid May when I go to the FSAE competition and talk to the GM engineers in person.
You could say that they jacked it but I don't believe it. Both knew exactly what the other was doing and through shared research (by SAE members and papers) they got what they needed from a technical standpoint. Then the R&D was all done seperately. It's just like all the inline 4-cylinders with 16v, they didn't SHARE the D in R&D, just a bunch of the R
.
Also, the hemi isn't an EXACT classic hemi chamber but it is very close. The valves aren't cantered on a 3D vector, only 2D, but it's still an excellent power maker with that exhaust valve angle. I bet those engines could be sweet talked into making 600hp n/a with just some nice bolt ons and a little porting.
