An audiophile's utopia [consumer tech audio]

The Sonos wireless audio streaming system works with a proprietary 802.11n type wireless network called SonosNet to prevent interference or drops caused by existing wireless Internet traffic. It can stream from any storage device on your network that supports the common Internet file system (CIFS), such as a NAS (network attached storage device). The user can be located using a Wi-Fi enabled device such as a smart phone. Alternatively, users can authenticate themselves via radio frequency identification. Thus technology companies have demonstrated that our audiophile's utopia is feasible.
