A network control system for an appliance has a software operating layer that is responsive to a plurality of appliance function calls. A physical user interface on the appliance is capable of generating directly some of the appliance function calls. A virtual user interface connected remotely over the network is also configured to invoke some of the appliance function calls. But the virtual user interface can further invoke one or more of the function calls that the physical user interface cannot generate directly.
