Aspects include systems, computer readable media and methods for remotely updating properties of Audio/Visual (A/V) performance nodes that can receive A/V content through a wireless network from a central content source. The central content source can maintain information about properties of such nodes, providing such information to a device configured with remote control software, upon request. The remote control device can accept user inputs relating to properties updates, indications of such being provided to the central content source for distribution to nodes whose properties were updated. Examples of updatable properties include on/off toggling, and volume controls. Updating such properties can be protected by passwords. The central content source can be configured as software executing on a personal computer operable to communicate over the Internet for obtaining access to streaming and/or downloadable A/V content. Remote control device examples include phones that can be networked to receive node properties data, obtain user inputs affecting such data, and transmit that data back to the central source.
