        Off topic a little... 

        But the metre (and hence inch) are derived quantities (variables) so all 
our footprints are totally useless! Do you hear   *useless*! 

        The speed of light, c, is constant.  Any improvements in the how fast light 
travels does not affect the number in metres per second.  The length of the 
metre is changed instead.  So there is no point in trying to design 
footprints as the next time a physicist improves the estimate of c we have 
to go back and update all out libraries. 

        I'm giving up and going to the beach....
