The previous chapter has delved into some of the bigger implications of free networks in relation to the overall historic development. It has described the overall development as an incomplete paradigm shift, characterized by an ongoing structural crisis of information society. This chapter starts with the question, what makes a network sustainable? On the surface of things it looks like the conditions for growth are better in rural areas, where there are no good alternatives provided by the telecommunications industry. Examples in Spain, Germany, as well as Greece show that there can be successful models that bring together community initiatives with municipalities. This appears to have worked less well in the USA where after a good start in the early 2000s hardly any wireless community networks exist. It seems that the relationship between rich and poor in the US is almost like the relationship between the overdeveloped world and the poor nations of the South. This chapter finishes with a more sustained look into selected projects from the global South.
