currency spend analysis vs. disease

-----BEGIN PGP SIGNED MESSAGE-----

readers are possibly familiar with the "Where's George" 
US dollar bill tracking site:
http://www.wheresgeorge.com/
also a Euro tracker here:
http://www.eurobilltracker.com/

a 26 January 2006 Nature magazine article is described here 
which uses this movement of money data to analyze spread of 
disease:
http://urlx.org/mpg.de/0551

i think the article mentioned is available for pay here online:
http://www.nature.com/nature/journal/v439/n7075/index.html
 _Travel: Fitting the bill_ by Rory Howlett

i offer AUG 2 to the first worthwhile (in my judgement)
review of said article to appear on this list.
