Edit: Oh and doesn't need dual-axis motor slaving as the screws are connected with belts and use just one motor.
Great minds eh? I realised about the belt drive about an hour after I wrote that. You can see the single motor in the pictures. I assume the long axis would be done the same.

For long thin work that's going to be a very solid design and with the option of a fourth axis up the middle would be the bees knees for fancy furniture legs and a myriad of similar stuff. With the right gantry design you might be able to achieve an unusually high Z axis lift without seriously sacrificing rigidity which would help with that kind of work.
