It's good to see at least some first-order thinking about the practical problems of organ cloning. To date, I've been thinking this will be the numero uno biotech breakthrough within the next ten to 15 years. Question: Have you worked through the question regarding time you pose here to a next-order approximation, Robert? Do you know if anyone's working specifically on these issues?
