Mesh networks please! Briar, Meshenger , heck maybe we need to make a cell phone app to provide internet connection sharing over WiFi and or Bluetooth ad hoc networks. Can it replace full isps? Almost never. Can it enable light text based things like emails, ordering supplies or cashless trxns? Maybe... The biggest problem is scale of course, having such a large geographic area would require most of the population to have this mesh app active at once plus several 'exit nodes' with access to actual isp traffic somewhere in other regions. IDK this is a spitball reaction that I considered not posting as it doesn't seem very thought provoking like normal HN comments but if it Sparks discussion then it will have done its job.
