FAQ: Is there a Z-Wave/ZigBee "iDevices Instant Switch" style battery-operated device available?

Just came across this iDevices Instant Switch and the form factor is fantastic. Basically a dedicated scene controller that fits in a rocker faceplate, but does not require a gang box to install and runs off battery. Does anyone know of a Z-Wave or ZigBee device that has this form factor? Currently using a lot of Aeon Minimotes for some scene control within rooms, but this would look a lot better for some particular applications. Specifically, fitting within an expanded wall faceplate.
