I believe AC3D does vertex smooth using all shared surfaces of a vertex.

You won't see the smoothing on a cube, however, because of the crease angle - you'll have to open the cube's object properties and push the Crease angle above 90 to see vertex smoothing in action.

Sounds like your base calculation is fine, you'll just have to account for the surface angle. Also, you won't be able to get away with a single vertex normal where you have mixed smooth/flat angles due to crease (i.e., the vertices at the edge of a cylinder where the top is flat-shaded and the sides are smooth).

Good luck
