Yes. Multiple dimmers can be programmed as 2 way, 3 way and n-way switches. Additionally, we are planning a stretch goal to create a lower cost accessory dimmer that could be used in place of the higher cost standard dimmers in n-way switch legs.
There are two components to a non-US version. First is voltage range. Our design is capable of handling 120-240V and 50 or 60Hz. However, mechanical requirements are different for various regions of the world. We are considering a stretch goal to design non-US form factors. More on this in the coming days.
