NetStreams Digilinx is the ultimate in audio and video.  They have come out with a new product that bridges the home theater and multi-room audio divide- the Theaterlinx TH100.  HomeToys.com has a good article on it, "A One Step Solution for Integrating Home Theater and Whole Home Audio". 

"Traditionally, a home theater and a whole home audio system (multi-source, multi-zone) are two separate systems where integration can become a costly and complicated process.  While the technology and products certainly exist to combine the two, the cost and configuration of such systems can be considerably more than most people are willing to spend.  Whether you’re talking about the  issues of conveying and switching signals, maintaining signal quality, or programming controllers to operate multiple devices from multiple locations, the task of integrating a home theater into a whole home audio system (or vice versa) may require more than most consumers expect or bargain for.  What seems conceptually simple and affordable can quickly become surprisingly complex and expensive – particularly in providing a GUI that is both full-featured and truly simple to use – causing some customers to just say, “NO.”"

TheaterLinX bridges the gap in two ways. First, it converts the line level audio from the home theater A/V receiver or processor into an IP stream for playback throughout the entire home over the DigiLinX network.  Secondly, the TheaterLinX also outputs line level audio from sources on the DigiLinX network for playback over the A/V receiver or processor in the home theater. The audio is completely synchronized – a key difference – with NetStreams’ patent-pending technology, StreamNet.
