Interesting. What really bothers me and pisses me off is the fact that they state that it would be used to augment a runners natural ability. Considering that most people approach a marathon by trying to do it as little time as possible I can only look at this as one of our institutions of higher learning trying to help people cheat. So much for ethics. I was expecting them to at least promote them as being developed with the express purpose of helping injured and handicapped people move about better but that seems to be a secondary goal.
