I forgot the details, but I was told about a project where offline PCs were installed in remote villages, equipped with wifi. A data-carrier-PC, also with wifi, was moved between the village and the city, where it could exchange data with the internet. The data-carrier-PC could be installed on regular buses or even on a bicycle.

ew0 suggested an interesting article in the Low Tech Magazine, How to Build a Low-tech Internet.
“WiFi-based Long Distance Networks”:
Although the WiFi-standard was developed for short-distance data communication, its reach can be extended to cover distances of more than 100 kilometres. … An example is the Akshaya network in India, which covers the entire Kerala State and is one of the largest wireless networks in the world. … Another example, also in India, are the AirJaldi networks which provide internet access to approximately 20,000 users in six states, all in remote regions and on difficult terrain. … An example is the link between Cabo Pantoja and Iquitos in the Loreto province in Peru, which was established in 2007. The 450 km network consists of 17 towers which are 16 to 50 km apart. The line connects 15 medical outposts in remote villages with the main hospital in Iquitos and is aimed at remote diagnosis of patients.
“WiFi-Based Community Networks in Europe”:
Despite the lack of reliable statistics, community networks seem to be rather succesful, and there are several large ones in Europe, such as Guifi.net (Spain), Athens Wireless Metropolitan Network (Greece), FunkFeuer (Austria), and Freifunk (Germany).
Delay-tolerant networks don’t require an end-to-end path between source and destination. Data is simply transferred from node to node. If the next node is unavailable because of long delays or a power outage, the data is stored on the hard disk until the node becomes available again. While it might take a long time for data to travel from source to destination, a delay-tolerant network ensures that it will eventually arrive. … In such networks, conventional transportation technologies — buses, cars, motorcycles, trains, boats, airplanes — are used to ferry messages from one location to another in a store-and-forward manner. Examples are DakNet and KioskNet, which use buses as data mules.
I do remember the sneakernet – meet up with some friends, hook the disk drives up to laptops, watch some episodes, and then copy what you liked for later viewing. Good times! 😃
