"Black" day of P2P protest on April 1?

Rumors are circulating in geek circles that some peer-to-peer technology companies (and/or supporters) plan to paint their websites black on Thursday, April 1 -- protesting recent efforts by state and federal lawmakers to crack down on filesharing. Lest anyone forget that Thursday is also April Fool's Day, some of the participants are said to be planning to blame the "outage" on this gag website for a fictitious "Copyright Enforcement Agency" of the US government.
