I am in a LDR and hence have a shared account. I also do spend significant amount of time away from my primary location. This is just going to be annoying.
Email, phone, password manager, ... any other internet based service.
Netflix is not like cable. Cable is provided by a physical wire connected to one location. Netflix is delivered over any internet connection. If I pay to have multi-device access, it should not matter where those devices are located.
