Thank you, Simon, for trying to clarify.
It's all very complicated, but not in the way you were explaining. The problem with porting this to Inkscape is the fact that Scriptographer is tightly bound to Illustrator. I did not have a look at Inkscape's Plugin API (I assume there is one), but I doubt that they are similar. Developing a Scriptographer for Inkscape would probably be even more work than it took to do the version for Illustrator, as I would need to simulate the behavior in Illustrator.
Therefore I don't think I'll be able to cover Inkscape, I'm afraid.
