Netgear is about to extend your AirPlay network with the Powerline Music Stream Box (German website). This means you can not only pump data through the power lines in your home but connect speakers to your Apple AirPlay network as well. (We are talking music streaming with iTunes or iPhone and iPad). The Powerline XAUB2511 comes with an Ethernet port and a USB port which talks to USB speakers and connects to a stereo using cinch cables too (adapter included). You may also use the USB 2.0 port to plug in a hard drive or a printer for easy network sharing. Price? 140 € for two Powerline adapters.
