Mainstream support for the notion of a donor organ marketplace...

Mainstream support for the notion of a donor organ marketplace...  I'm used to my ideas being considered a bit wacky (ok, very wacky).  I've long believed that a market for donor organs made much more sense (including ethically and morally) than the system we have today, but I know that's a distinctly minority view.  Still, when I see a mainstream intellectual supporting the notion, it cheers me up!
