How does it follow that companies will turn to building a new network due to concerns about the NSA in the US? This takes for granted that the privacy concerns outweigh the economic ones. Foreign countries have just as much to lose as the US if internet-based commerce across borders is stopped. I worry more about the internet breaking up due to foreign governments' desire to censor and isolate their internal networks, not because they are worried about the NSA.
