Great Idea if it doesn't already exist

Is there a way that I can place my participant's window at the top of the screen instead of side-to-side or at the bottom? Most people's video cams are located at the top of their monitor. By placing my customer's window at the top of the screen near the video cam, eye-to-eye contact is maintained and appears more realistic. Nothing worse than a salesperson not looking you in the eye when talking to you. If I am looking at them at the bottom of the screen while talking to them, it appears as though I'm not looking at them at all. 

Any thoughts???
