Tim,
        If you feel so convinced that exact screen - real world inch
calibration is possible, I would like to see how you would do this,
programitically or non-programitically. Tim, you have lost ground. Please
provide evidence(in form of code or otherwise) upholding your claim.

What do you mean by "measure the screen" approach?
thanks
vipin
