U.S.-Backed 'Mesh' Networks Help Dissidents

The State Department provided $2.8 million to a team of American hackers, community activists and software geeks to develop the system, called a mesh network, as a way for dissidents abroad to communicate more freely and securely than they can on the open Internet. Since this mesh project began three years ago, its original aim — foiling government spies — has become an awkward subject for United States government officials who backed the project and some of the technical experts carrying it out.
