Despite legal setbacks, the music industry is having another crack at those pernicious fileswappers in Canada.

“The Canadian Recording Industry Association said on Friday that it had filed court requests earlier this week that seek identifying information for subscribers at five Canadian Internet service providers. The information gained from those requests would be used to file copyright infringement lawsuits against people who had made large amounts of music available for upload, the group said. “

All this follows on from a Canadian court ruling a little while ago that downloading from services such as Kazaa appeared to be legal under Canadian law. Of course, the music industry disagreed, although this time they appear to be focussing on people who upload as opposed to download.
