I don't think "outside the box" when "inside the box" is the preferred method. I cant think of a single instance where I have read anything regarding optical "distortion" where they were NOT referring to geometric distortion. The other types of abberations are called abberations, chromatic, spherical etc, but they are referred to as abberations, not distortions. You cant just go "outside the box" because the terms are conventions and people will not know what the hell you are talking about if you do "your own thing". http://www.angelfire.com/biz/Leica/page15.html
