well, I wish Sony all the best of luck. Once information of this type gets out on the web, its nearly impossible to remove. The problem Sony has that "reverse engineering" isn't exactly illegal. Now, they have tried this before and look where it got them: case thrown out of court because the expert witness torpedoed their case.
They might have a case for copyright infringement but with as many copies as are floating around out there, its going to start costing them more than its worth to pursue all the possible litigants.
Perhaps Sony should open source their software and get a lot of "free help" improving it. That would not only earn them increased profits, but also loads better in Public Relations credibility.
