aah, op here. So right now I've only got the 100 or so keyboard ascii chars. The reason is that there is no software api for v-carve lettering. I've had to write a script that's basically a point-and click windows macro for each possible character, then compile the whole text with appropriate kerning. The process already takes several hours for each font, plus hand-corrections for any vector problems with the export.
At a lower level this type of v-bit carving is much more difficult compared to 2d operations like pcb trace milling. There are various tricks (http://s485.photobucket.com/user/defaultname000/media/butter...) you can use for computing vector offsets of arbitrary paths, but for v-carving you need to get the medial axis as well.
There is an another limitation - any individual stroke wider than about .09" requires 2 passes to cover, which is not ideal since I'm basically selling machine time. Adding arbitrary symbols would likely increase my cost.
edit: I've gotten the center comment from a few people, I'll see about changing that
