A cheap, straightforward approach http://www.partsexpress.com/pe/pshowdetl.cfm?&PartNumber=300-830&DI… There is another way to do it by modulating the audio sources onto a coax wire and using a TV or VCR to tune in the source that you want. This is very easy for non-techinal people to figure out, but it doesn't sound as good. Here's the really cool Linux approach you're looking for: A linux server with an RME HDSP card (12 stereo inputs on 3 ADAT ports), 3 8-channel A/D converters, and some kind of software (icecast?) to serve up those 12 stereo streams in near-realtime. The clients would be made up of an embedded fanless Via EPIA mobo (analog or digital stereo outputs) with a touchscreen and some client software (MythTV or even XMMS). If there are any investors out there who want to make this work, give me a call! -Ben Loftis
