... Did you by chance browse through the rest of the Egg-Bot wiki [1] (since the original question was referring to its smiley tutorial)? They describe an alternative method to generate line-based shadings (though not the same technique as used in the art of Duerer et al.):

It is based on stippling and aims for a single continuous path (TSP) instead of hatching with closely spaced parallel lines, but might still provide some interesting ideas and links... (and includes a set of python scripts to generate SVG output based on a bitmap image with the stippling information).
Interesting approach! Might have to experiment with it one of these days :)
