Despite winning this battle, the war against file sharers at universities continues to be contentious. Many students, and even some university officials, feel that the RIAA has repeatedly overstepped legal boundaries while pursuing students on college networks. At different times, various institutions have complied with subpoenas without comment, fought the subpoenas in court, or supplied Limited information.
Unfortunately, no clear Federal guidelines exist for the mass lawsuits being filed regularly by the RIAA exists. This has resulted in quite a bit of controversy, and a few very interesting defenses, as defendants try to find areas where RIAA tactics cross the line between uncomfortable and illegal. As long as the lawsuits are being filed, expect the interesting defenses mounted by some defendants to continue as well
