This was in March 2007, as we were beginning to think about how we would react, how we would build this system. Richard came to those meetings. He was consulted on the phone. He was a prolific writer. He wrote after the exchange about which I'm talking. He felt passionately about these views. He wanted us to move very quickly. We moved as quickly as we could, and a lot of his advice is incorporated in what we ended up doing.
