Basically, we are doing a multizone audio system with a pc based control system and the pc doing double duty as a music server. The plan is to use various touch screen interfaces for main room theater control, multi room control and to view music content on the pc/server. Basically, this is trying to do crestron/escient economically. I do all of my friends work gratis anyway and I;ve been wanting to try IP based control anyway. I was working with Premise systems but they are in a state of flux to say the least. I am looking for software and hardware recommendations
