The streaming sites that provide tv services for those who have decided to only get internet should never - ever be shutdown e.g. justin.tv and ustream.com. It is up to the site owner to remove any media at the request of the media rights owner. Watch Movies Links changes server addresses almost every 2 weeks to bypass ICE and Backup everything every single day to keep content. These sites will eventually transfer all there streaming media to a differient country e.g. Ukraine. I do not know every single ISP around the world but when IP6 is deployed globally it will be extremely difficult to isolate. Peerblock is my favorite friend and it has stopped several IP4 addresses and IP6 addresses have not been gone through or archived as NARCS. ARIN is responsible for the IP4 addressing and the US has most of the IP4 market from what I can find.
Homeland security and ICE should have better things to do by protecting our borders, non-tax paying illegal immigrants and securing our postal - UPS - and FEDEX packages that enter the US. When the Terror Threat model was came about, absouletly no one knew what to do when it was raised or lowered. Ron White said it best. Have to levels, 1. Get your survival pack and Gun. 2. After leverl 1, Load your gun and protect yourself.
