Why don't we, through /., set up a site, aggregate information about similiar cases and build up a body of evidence to "[...] show that the RIAA engaged in serial bad-faith lawsuits [...]". In the long run, the space could serve as a place for debate on the current copyright regime, the inflated monetary value assigned to the songs/movies downloaded, etc.
It seems to me like Groklaw
would be a perfect place for this sort of activity. After all, isn't it the sort of thing they did in the early days of the SCO trial?
