Sorry, I didn't have time to reply when I bookmarked this thread, I only remembered about it when you posted your latest comment. I thought it was
interesting and watched some of the video when I first visited. I thought for sure others would comment and that would remind me to revisit, but I
guess that didn't happen. I did watch most of the video tonight and I find it interesting also. I don't know how some really cool threads like
this slip through the cracks.
