This stuff is all good as long as its well documented which genes were changed and why. Because copyright (or patents) (or even (worst of all) trade secrets) on human DNA is the worst thing that can happen to our human society. We don't want only the well born to have better genes. But of course this won't happen. There will be a strong gene copyright lobby, and it will demand DNA to be copyrightable, to make research pay off.
Also, we should think of the possible pressure future parents may be in, in giving their children the best genes. Perhaps one day (rather sooner than later) we can change genes of living humans, too, e.g. with viruses, and then at least you can revide your parent's choices about your body.
