Location-Based Push Message?

[Mike Kerner]

To answer John, indoor navigation is currently not possible with wireless
devices, but there are companies working on this very topic, including one
that claims that they can use the peculiarities of the magnetic properties
of the mantle to tell a cell phone their exact indoor position.  There has,
understandably, been a lot of interest from grocery chains and the like, as
you might expect.

Monte, I would also be interested in the capability you are describing.  So
I take it you are not relying on location services for this functionality,
or are you?

On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
