You know, I hadn't thought about the corporate licensing angle. Many businesses could be huge allies in the fight against copyrights. Every bar, elevator, mall, waiting room, that even plays a radio broadcast is breaking the licensing terms. Replaying a radio broadcast in a business or public setting isn't covered under the radio's broadcast license so the business playing the radio needs a license. Same for streaming, playing CDs, having televisions in a sports bar. Hell, the ASCAP site makes it sound like every cover band playing an ASCAP artist's song in a bar requires that *bar* to have a license or they're liable rather than the band playing the song.
The only reason bars, restaurants, malls, etc aren't sued as often as individuals on the Internet is that they're harder to track down. This almost calls for a "public good" group to document these infringements and submit them to ASCAP, BMI, etc... maybe then they'd sue enough people with money that we'd get a lobby to revoke their power?
