My presentation was just a bunch of PowerPoints (done with Open Office), 
so there's not much to it. You can see the relevent portion of starting 
here: http://bennett.com/blog/Presentations/img18.html

Bob Frankston was on the panel with me, and he can correct this if need 
be, but as I recall there was a gasp in the room when the slide with the 
peer list came up; nobody knew finding pirates was so simple with 
BitTorrent.

Regarding TCP Resets, we've learned from the Comcast example that they 
can be generated by a machine no more powerful (or expensive) than a 
standard PC.

I believe systems like this are a rational response to rampant piracy.
