White House Pressuring Registrars To Block Sites

While the Senate is still debating a bill that would force registrars and ISPs to block access to sites deemed "infringing," it appears that the White House's IP Czar is already holding meetings with ISPs, registrars and payment processors to start voluntarily blocking access to sites it doesn't like. Initially, they're focused on online pharmacies, but does anyone think it will only be limited to such sites? ICANN apparently has refused to attend the meetings, pointing out that they're "inappropriate." Doesn't it seem wrong for the US gov't to be pushing private companies to censor the internet without due process?
