Perhaps the real thing we should all take away from this is a lesson in the importance of involving your family in knowing what your wishes are. Organ donors have to do this already (make sure their family knows that they want to be organ donors so some hyperanxious relative doesn't derail the process). Arguably, those who would NOT want to be kept alive in a perisistent vegetative state backed up by medical imaging (as is the case here) that shows beyond a reasonable doubt that recovery is not gonna happen, should tell their families.
I have told my wife that I would NOT want to be kept alive on a machine in this situation, and she's told me the same. The next step is to let my parents know, as well as write it down (I believe it's called a 'living will?').
