Ok, this is going to take you into a whole new place but. Cinemaronline.com has a product called Main Lobby. I cannot speak highly enough about the product or the community of users. It was created for home theater and automation and works much like a crestron system would. I personally use it basically as a touch screen control for my whole home theater. I run it as a client/server setup with my tablet PC as the remote and the htpc as the server. You know what...just check out the site. If it will work for you, the product will sell itself.
