Can't answer your question but wish I had time to do it. Thanks for the link, I rarely look at stuff like that. Wow!
I have always wanted to see what could be done with virtual solid CAD; You have tools on a rack and use them to carve-up a block or maybe a fire-hose plastic extruder. You could have chain saws, jack hammers, flamethrowers to make fillets and chamfers, using all of these to work on a block 1mm square. Maybe a virtual milling machine or EDM to prove concept of a Mold and then watch the Mold run.
