I almost entirely agree with Inter FX which tends to be the norm here... why not just calculate it yourself rather than punching numbers into a black box and hoping that you get the right answer, plenty of people have had to solve this problem in the past (luckily we're not the first suckers to get stuck with working on maps :).
So yah here's how to calculate the distance http://www.movable-type.co.uk/scripts/latlong.html make sure when doing your translation/porting from javascript to actionscript you check out the atan2 function as the parameters may be flipped depending on the language/implementation. I'd say the earth is round and is also a sphere :), it just depends on how you slice it: 4. having a circular cross section, as a cylinder; cylindrical. 5. spherical or globular, as a ball. However I wouldn't say it's a "sphere" directly as that's what all this non-sense about radius and different standards for Lat/Lng are all about, depending on altitude away from the earths center (up on a mountain vs below sea level) you have a different radius and therefore a different sphere, further the earth is flattened by it's centrifugal force so the "sphere" is larger at the equator from my understanding. http://www.cotf.edu/ete/modules/msese/earthsysflr/exact.html Anyhow generally speaking I agree just roll your own function for this one.
