Draw Scaled flipped normals for cartoon outline?

I saw "Cell Shading Tutorial" thread.
i tried it with 3dsmax and i works well.
the outline looks much better than drawing edges for outline.
instead of making model with scaled fliped normals,
i want to modify engine to draw mesh with scaled and flipped normals.
void TSMesh::render(S32 frame, S32 matFrame, TSMaterialList * materials, const MatrixF *objectTransform)
{
// draw normals
// draw scaled flipped normals with black color
}
how can i draw scaled flipped normals with black color for outline??
i don't know opengl, yet.
please, any advice!
thanks.

First, turn off texturing and lighting. Then, set the vertex color to all black. Then, change glCullMode from CCW to CW (or is it the other way around? I forget). Then either bind a shader that moves the geometry based on the normal, or do a software transform on the vertex array to move the vertices out. Then draw that.
Then set all the state back again.
