I want to integrate into my theater a HTPC with a dedicated lcd touchscreen display that will act as a home theater controller and a second output that will show video output. On the touchscreen I'd like to have an easy to navigate and use GUI that would incorporate automation events such as sending IR signals to lights, projector, receiver, etc based on user input. Basically, a wired version of a remote control but one that updates with the computer for browsing windows media center. Has anyone tried doing something like this? Any ideas how to make something like this happen?
