The internet is neither neutral nor private, in case you were in any doubt. The US National Security Agency can reportedly collect nearly everything a user does on the net, while internet service providers (ISPs) move traffic according to business agreements, rather than what is best for its customers. So some people have decided to take matters into their own hands, and are building their own net from scratch. Across the US, from Maryland to Seattle, work is underway to construct user-owned wireless networks that will permit secure communication without surveillance or any centralised organisation. They are known as meshnets and ultimately, if their designers get their way, they will span the country.
