Hi Paul,
I was curious. What do you think are the chances of correctly (correctly implying a strict respect of independence between logical and physical layers) representing some unique identifier otherwise than by computing it according to a mathematic model? Did you by any chance give any thought to that? Received on Fri Jul 13 2007 - 12:29:33 CDT
