Highly so.
It wasn't a serious suggestion of mine - just a way of looking at the problem in
a different light.
I guess you know the old story of :
"How can you determine the height of a skyscraper with a baramoter".
Rather than try and measure the difference in air pressure at the top and at the
bottom, a more accurate method would be to smply ask the janitor, and offer the
baramoter to him as a present for his spouse. :-)
