If this technology gets to the secret services or terrorists, it could have very serious consequences. Why geneticists have banned the experiments on human beings? Because technology allows us to artificially raise soldiers. I think you need to ban this technology for the same reason.
Tech like this will arrive at some point. It won't be possible to uninvent it either. Never in human history has everyone agreed to not research and create something potentially advantageous. Someone, somewhere will do it.
Nothing new here. It's basically the same thing as one proto-human figuring out that he could pick up a bone and crush the skull of a fellow proto-human. Covered in 2001 among many other fables.
Witch burning and firing squads in their various historic forms were invented to discourage improper use of technology. If the unwashed masses can have a say in the construction of rule-of-law and it's implementation, they may arrange some protection for themselves. If not, sad day for that class. It's an arms race of sorts, but again, it's nothing especially new.
