The official answer is yes, it is fully supported save for the color buttons on the MXW-920 which you would have to add for each device manually.

This is also possible with the MX-iOS > Android (and vice versa). So you will be able to "Clone" an iPhone to an Android Phone program and not program twice.

You should see this trend continue moving forward in little ways here or there with the Complete Control line similar (but not quite the same) as has happened with the Total Control products.
