Offset curve based on surface normals

Since nobody responded, I did my best to approximate a solution.

I divided the curve-on-surface into an arbitrary number of points, and then used the evaluate surface component to retrieve the surface normal at each point.

I then drew a line from each point to the offset surface, using the corresponding surface normal for direction. I then interpolated a line through the intersection points of the second surface. 

I'd like to think that there's a cleaner and more accurate way to do this, however.
