These stuff exists, but it usefulness depends on the administrators. I was really surprised when a couple of years ago visiting Tigre, a city north of Buenos Aires, argentina: There is a huge river delta there, the Tigre delta and the people living in the small islands formed by the many branches of the river have a sort of local internet with their own news sites, wiki, etc... as well as access to the worldwide internet. Another interesting fact is that some of this island houses have electricity but no drinkable water, they have to carry it from the city docks
