Andre Meyer posted here about software for spiral bevel programming on a 5-axis machine. He may have something for helical cylindrical gears. Here is a link to an article about his contribution:

I agree with Tom Ramsey. The program modeling geometry is not so easy, whether you go with a rack form cutter and incrementally roll the gear, or you try to cut it with an involute shaped cutter.
I don't know, but it seems like using a rack form cutter, and taking multiple passes to generate the involute would be simpler to program - just a thought.
Makes a hobbing machine look realllly good :^)
