I was talking with Steve Polge back when he was still with IBM. He did send me a version of the Reaper bot source at
       that time. We agreed that it was for research only and that I would not release or use it without his permission. When he
       changed jobs shortly thereafter I figured it was best for both of us if I didn't even use it as a research base. So, even
       though I did have the source I never inhaled.. ummm, used it. Nobody else here even had access to it so I can safely
       state that nobody at id has ever seen the source (I hadn't yet had the time to look at it when he made his job change). I
       just wanted to make this clear so that Steve doesn't think that there's something fishy going on. He's a good guy doing
       good work.
