This news report says it all:
” The U.S. Supreme Court on Tuesday declined to consider whether recording-industry investigators may use a favorite tactic to find out who may be copying their songs over the Internet.
The Recording Industry Association of America had invoked a 1998 copyright law to force Internet providers like Verizon Communications to turn over the names of customers they suspected of sharing their copyrighted songs.”
The RIAA can go screw themselves let em do it one individual at a time. [cNet]
