The problem is not the latitude/longitude. It would be trivial to 
compute the great circle, thus the length of the trip between A and B 
and divide it in smaller pieces to get 1-mile-distances.

  But unless you own an Aircraft & are important enough to take flights 
the direct route without air traffic control getting mad at you (aka: 
you are George W. Bush or some other bigwig goverment guy), this won't 
do you much good. What you needed would be a vectormap of the streets so 
that you could do route planning. Which is expensive to get.

So I guess you are better off trying to find someone who offers that as 
part of the service.
