IP Speakers

I read that announcement as well, not sure if it was on /. or digg, but it is supposed to be true IP, and it has a built in AMP as well.
An open architecture StreamNetâ„¢ card (optional-not supplied with speaker) welcomes integration with any system capable of streaming packet-switched audio in WAV or MP-3 format and TCP-IP control.

I can't imagine how this is going to work well, but I am sure they must have figured this out, and Polk has a great reputation.
Those are very expensive. I wonder if anyone will create a cheaper version. I wouldnt mind having a few IP speakers just for TTS but at a much lower cost.
