RIAA boss: Move copyright filtering to users' PCs
Sherman's a sharp guy, and he's fully aware that filtering will prompt an encryption arms race that is going to be impossible to win... unless users somehow install the filtering software on their home PCs or equipment.
This means moving the filter out of the network and onto the edges (local machines), since it's at the edges that decryption and playback occurs.
Sherman knows it's a tough sell. "Why would somebody put that on their machine?" he asked rhetorically. "They wouldn't likely want to do that."
The only way to make it work is to mandate the filters or have ISPs mandate that users install them to get on the Internet. The consumer backlash from such a plan would be like the force of a thousand supernovas, and it's hard to visualize this happening.
