Now think doctors and nurses running around the hospital with this, ticket checker/conductor on Amtrack, a teacher in a classroom taking attendance, anthropologists in the field, mine and oil site inspectors, most importantly think third world's extended health care workers (docs are a few so they train folks to be half-docs and send them all over - millions of them - imagine one doc sitting in Addis Ababa, Ethiopia getting real time data from 1000 workers and only bothered when a red flag is raised by a worker tending to a pregnant woman going in labor shortly - UN orgs give a lot of money for infant mortality - as a matter of fact for all 7 UN's Millennium Development Goals).
