A Sony exec claims that they’re going to put infrastructure in place all over the Internet to block Napster, everywhere from your ISP to your personal PC. There are lots of problems with his plan. You can start out with the fact that there are plenty of alternatives to Napster out there, and if they block all of them, all someone has to do is create an alternative that uses email or HTTP as its transport method. Will they block that, too? And that assumes that Sony has the pull necessary to put in the hooks to filter out this stuff. Obviously the stakes are high, it will be interesting to see what the recording industry does wind up doing.
