[ NNSquad ] Re: Speculation, how AT&T can implement "copyright filtering" without wiretapping/dpi...

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.
