From AP/Ted Bridis. The article says these are methods to track downloaders, but I was under the impression that at least for now, they are tracking people acting as uploaders by posting files, not downloaders.

Rich Kulawiec says, "Wow. The RIAA has discovered checksums and the Unix/Linux 'sum' command." Wouldn't it be terrific if the RIAA used some of this brainpower to make good legal download services, using a nice easy interface offering a wide range of music at a reasonable price, compensating artists fairly and making it cooler to download legally than not to do so? Course there would always be a few shoplifters, but that's the cost of doing business across many industries.
