Touch Screen Monitors

With all of the frustrating results from Avid’s PT Control (now Avid Control) and the Cubase IC app, I was wondering if I couldn’t just get a touch screen monitor to control Nuendo DIRECTLY. I was thinking that I could “clone” the Mixer window and use a smaller screen as the remote control for when I needed to record. Since I haven’t seen anyone suggest that option, I was wondering what the drawback was to trying that approach. :question:
