Comcast Sued Over P2P Traffic Blocks

Comcast has been hit with a lawsuit over its network "shaping" tactics for P2P and Lotus Notes traffic.  Is anyone surprised?  Comcast has steadfastly denied any such thing.  It's one thing to allege, and another to prove.  There has to be something more than the original report and tests by the AP for this to go forward.  Read it in Computerworld.  Is AT&T going for the same kind of network management?  Read about that here.
