You've probably seen this already too, but just in case:
http://www.webmonkey.com/webmonkey/05/32/index4a_page9.html?tw=programming

This is the article where the creator of zipfinder.cfc describes what he's
doing and this page in particular talks about Rlongitude and Rlatitude and
how they are calculated and (all-too-briefly) why.  
 
Hope this helps (and sorry for the distraction if it doesn't and thanks
anyway for getting me to this article)!
