Sonos ZoneBridge Would Complete Wireless Network

Today, the FCC leaked some info about the Sonos ZoneBridge, a wireless device with little or no practical details. But people familiar with the system understand that such a product could fill two specific needs:
• Since Sonos requires one hard Ethernet connection to a router, the current system requires you to use up one of your ZonePlayers ($349 and up) for that purpose. A cheaper (maybe even as low as $99) Wi-Fi Ethernet bridge would solve that problem.
• Since you can carry the Controller throughout the house, especially the big-ass houses of affluent Sonos owners, network-only non-music-playing ZoneBridges could be used to enhance the mesh network. [FCC]
