great-circle

I have a Latitude, Longitude, and a direction of travel in degrees true north. I would like to calculate if I will intersect a line defined by two more Lat/Lon points.

I figure the two points defining the line would create my great circle and my location and azimuth would define my ray (or possibly a small circle).

Any ideas?
