With as many as 49 bloggers, online editors, and web based reporters behind bars as of the end of 2006, technology companies and human rights groups are collaborating to create an Internet Code of Conduct designed to protect free speech and privacy online.  Participants include Microsoft, Google, Yahoo, Vodafone, Center for  Democracy and Technology, the Electronic Frontier Foundation and the San Francisco based Business for Social Responsibility.  The focus of the code will be to hold companies accountable if they cooperate with governments to suppress free speech or violate human rights.  You may recall Yahoo being in the spotlight for supposedly helping the Chinese government trace Shi Tao's email exchanges.  Shi Tao was subsequently sentenced to 10 years for leaking state secrets.  More detail here.
