From Marantz (http://us.marantz.com/DAvED_press_rel.pdf):

Marantz America, a world leader in advanced home entertainment solutions, has introduced a major innovation in multi-zone audio distribution, “DAvED” (Digital Audio via Electrical Distribution). Originally introduced at CES under the prototype name “PLAC,” DAvED (pronounced “David”) is comprised of the Marantz ZR6001SP system, which includes the ZR6001 Audio/Video receiver, and the ZC4001 Client. When combined, these two high-performance components make it easier than ever for consumers to set up a multiple room digital audio distribution system in their home – by actually running all their favorite music to any room in the house via the existing AC power lines in their home.

How DAvED Works…True “Plug and Play” Audio Networking
Designed for easy and quick consumer set-up, Marantz’ new DAvED technology is an ingenious method of bi-directional signal communication by using AC power lines as a transmission channel, superimposing high frequency signals over the AC power line. Multi-room communication between audio components equipped with DAvED circuitry begins the moment they are plugged into any electrical outlet, offering simple plug-and-play audio networking.

So it's essentially a factory-installed HomePlug audio distribution system. I believe this is the first time this has been done for purely digital audio.

The first receiver with this is the ZR6001SP (http://us.marantz.com/Products/1545.asp), which includes a ZC4001 Client (http://us.marantz.com/Products/1549.asp), also available separately. High price though, $1299.99 for the receiver (which is based on the SR5600 selling for $649.99) and the client is $329.99 - yes, more than a Squeezebox. But it includes an amp and speakers.

In fact, the client may be very much what a Squeezebox boombox might look like. It also gives you an idea of how much it might cost - keep in mind, DAvED is a lot simpler than a Squeezebox.

It's an interesting, unusual approach though, and in my mind much more interesting and revolutionary than the iPod boombox.

BTW this is not new, the press release was out January 31st, but this is the first I've heard of it.

Very interesting - except for the price. The client isn't exactly my cup of tea, and the display is way to small (SB has spoiled us!). The holy grail is still the hand-held visual remote (Nokia, Treo, PDA, a la u-no-who), and I don't see how they can implement that with the totally integrated power-line networking without overlaying some sort of wireless!
It's a nice tidy system, I can see where it would work very well for a lot of people!
