John and all following this story,
Sorry for double posting.But, a thread has been going fairly strongly at TDF on this subject today.Alsyoyo has just recently posted an interesting article on this. I guess we'll have to see though Dr. MCcarty's take on it when he gets back.. you and others interested in this may want to keep an eye on the link...as I don't know how frequently you guys pop in there...
