In places lacking internet bandwidth, people could run pubs in hackerspaces, schools, offices, homes, Actual Pubs, etc. A pub in a place that people frequent would gossip messages for the people, so they would not all need to connect to the internet all the time. Even the pub itself doesn't have to connect to the internet for it to be useful, as it would still help messages spread when people connect to it. As long as someone in the network connects to the Internet at least once in a while, people will be able to communicate with the broader network. With this architecture we can make more efficient cooperative use of network bandwidth.
