Thanks to all the replies to my earlier post i managed to approximate a
solution to my problem.
But it also raised another question.

If i have 2 'line' given by lat/lon, something like A(lat1, lon1, lat2,
lon2) and B(lat1, lon1, lat2, lon2) how can i calculate the (lat, lon)
where
both lines intersect?
(if they do in fact intersect).

What's the application? What problem are you trying to solve with this?
