I have suggested Arduino Supported be implemented in the demand forum area, mapster.
SSDC has just implemented it, and the other factor is it can be tapped for other elements. I've got some RGB LEDs under SSDC control, but I could tap it to work on another project where as soon as the green lights are active, it'll release the roller bars on the old style "Rev Start" sections. Arduino is also a lot cheaper compared to some options.
The same could also be true of RFID Reader options.
