I don't think it will pass, mainly because I don't see how SOPA would stop anything. Anyone could set up their own name server, spread around by e-mail how to use the new name server, and call it a good day. Then there truly would be a, "computer underground," once again. I promise you, nothing will ever stop people from ripping content, SOPA would only temporarily stop the means by which that content is shared. This isn't going to do anything except hurt legitimate e-businesses.
