Well, we did it in my biology degree many, many years ago, I know it has been taught for a couple of years at least as an A-level biology ethics thing... it is unethical but then so is most of the world, at least this may have a positive outcome.

I should have been asked for consent before being carved up, yet no-one thought to do that. Consent and doctors just don't happen, IME. That's the medical world and it won't change very soon.
