Yes, it would be interesting to hear from all the authors how they decided to publish the HDCP crack, first at a recent conference, then to publish on the Web -- as far as I know none besides Scott Crosby, the principal author, agreed to publish on the Web. Scott, a student at CMU, first broke HDCP program before Niels Ferguson refused to publish his cryptanalysis of HDCP due to DMCA: http://cryptome.org/hdcp-weakness.htm Scott said at the time of the initial break that he was fearful then about being punished under DMCA and even more so now. He says he now agrees with Neils to not publish additional cryptanalysis under threat of the DMCA. It is possible that the HDCP owners don't give a damn for the program was openly published and there's been no public complaint about Scott's first crack, Neils or the latest. To be sure, that lack of initiative might be due to fear of cyberterrorism initiated by Richard Clarke or it may be due to confidence that the FBI will take care of all the nation's problems in about 150 years.
