Just a quick thought experiment (because my networking expertise is limited):<p>Take a single computer at the edge of town A. It&#x27;s the only machine in town A that can connect to the next town B, because of the distance between town A and town B. All traffic in town A now has to route through this machine to reach town B. How will a single machine achieve this?<p>Even worse, what if the two towns are too far for any connection other than a centralized style connection (large wires on a pole).
