Dan's talk at Black Hat on 'The DNS Bug' aka CVE-2008-1447 was packed. By this time I had worked out that BH attendees, much like Catholics fill up from the back, so you can usually just walk to the front and find a seat. I did and ended up three rows away from Dan and his podium, a decision I later regretted.
It's a long entry, so I've bold'ed the key parts of my rant.
