I say members, but I'm not sure that's correct as I think they're still working out the agreement under which each member agrees to operate. Apparently there is a lot of secrecy involved in the process and people like have complained that the Obama administration haven't even included most of the members of Congress in the details but companies like like Halliburton, Chevron, PHRMA, Comcast, and the Motion Picture Association of America are all being consulted and made privy to the details.
However a draft version of the agreement was leaked recently and apparently there are provisions that compel members to require ISPs to act as monitors and enforcers on behalf of the government and the owners of Intellectual Property, far beyond that which the US has required in the DMCA. For instance:
Three-strikes policies and laws that require Internet intermediaries to terminate their users’ Internet access on repeat allegations of copyright infringement
Requirements for Internet intermediaries to filter all Internet communications for potentially copyright-infringing material
ISP obligations to block access to websites that allegedly infringe or facilitate copyright infringement
Efforts to force intermediaries to disclose the identities of their customers to IP rightsholders on an allegation of copyright infringement.
I encourage people to put links to petitions in the comments area that people can sign who want the Internet to stay free. The next meeting is on May 12-15, 2014 in Vietnam.
