Do you have plans to support WGS84? What about Vincenty? any system that operates on ellipsoid can be suuported actually it is a PE-90 implementation (Parameters of the Earth 1990) however the parameters of ellipsoids of PE-90 andwgs-84 are equal +-tolerance in the end you can define your own constants (except pi)
vincenty is another bessel derived method it is actually very ancient (and less accurate than mine) however i borrowed some ideas from there -- Pavel
