The Recording Industry Association of America (RIAA) has been pursuing a high-profile campaign against P2P file sharing that stretches from college and university campuses to the cubicles of corporate America. On March 12, RIAA President Cary H. Sherman sent letters to 300 companies warning that “significant legal damages” could result from employers and employees who had already been identified via their IP addresses as having conducted music downloads using their respective corporate networks. AP reports that “the letters point out the copyright owners can collect up to $150,000 per song copied without permission, plus legal fees and profits earned by the infringer, and that the equipment used to make illegal copies can be confiscated. ”
