Hi, I am interested in this too. I have been silent here for a long time, (and was never really active either). But this is something where I might, semi-intelligently, help. :-)
Long ago I tried what openscad could do with substracting a cylinder moving along a path. I wasn't impressed with the speed. Unless things have really changed I don't think this will work. Anders' solution however, is something I was thinking about but couldn't really envision how to get started. If there is someone picking this up I would like to help. Although I am not certain how helpfull I will be. I can at least provide complex toolpaths. I am a (siemens) NX user and wrote all postprocessors for the machines we have at work. So, I do know a bit, but very specific for NX of course.
