Accepting because this is what we ended up doing and it was accurate enough for our purposes; I believe it was much less than 1% off for the area of Colorado.

comment How to compute geodesic area in GeoDjango?
Can you summarize the algorithm that JavaScript code is using? For example is it doing the standard area-of-a-polygon computation with (non-ellipsoidal) geodetic distances between the points? Concise explanations of the principles are a lot more helpful to me than lengthy code to wade through....

Sadly, there's no PostGIS in the system. The polygons are computed in Python and we need the areas without a database roundtrip.
