I am interested in this as well.. I just wired my basement for 5.1 and my rear speakers would be at about ear level when standing, so if thats the case I am in good shape.
Usually most receivers these days come with a mic that you can plug in and place it where you will be sitting, and it will calibrate your surround based on tones it plays one channel at a time.. It would probably adjust the rear levels based on distance and height.
