Andrew Bridges from Winston & Strawn is speaking now, taking a decidedly anti-DRM stance. Among other things, he's pretty clearly mocked the standard plaintiff's argument that lack of integration of DRM necessarily makes application vendors liable for contributing or encouraging infringement (I'm sure he used much more precise wording than mine.)

But what was funny was watching some of the reactions, particularly what looked to be disapproving comments going back and forth between Tom Rubin of Microsoft and Victoria Bassetti of EMI, who clearly didn't agree with Mr. Bridges' comments.
