Hey Mitch --- great ideas. I do have a question. I was looking at this product 4--_1 output , however I am looking for a 1 to 4 arrangement. My PC has terminal services running and pumps out MP3 tunes to different speaker sets. I wanted to use your product which would allow me to softswitch via your USB app interface (which is great I must add). AT present I use a manual switch - with your product I could simply login to the computer using TS and change the switch from A to B using your app.
Any idea where I can find one of these gadgets. So far you are the closest to what I need.
