I would like to set up a simple Multi-room audio system that is PC based. I want to be able to independently control audio in three different rooms. I only want to play back CD's or MP3s that are currently stored on my computers hard drive. I would also like have small LCD Pads in each of the three rooms for control of the music, play list and volume...? I know you can buy expansive systems that are designed solely for this purpose but is there any way to do this with MS Windows and some reasonably priced software and hardware. Any suggestions would be great, thanks!
