3D printers and DMX controlled lighting fixtures have a lot in common. A modern lighting fixiture is just a collection of servo motors, fans, and now adays LED driven optics. DMX is a very simple serial protocol with plenty of established librarys and the rs485 boards are extreamly cheap. Any modern 3d printer main board and lcd would make the perfect fixture control board for designing and building your own lighting fixture. This would also reduce developement costs in the lighting industry as most the components are custom made currently.

So you would want Marlin to read off the DMX bus and turn the DMX commands into servo/stepper/relay controls? Interfacing the steppers/servos seems reasonable. Have you tried wiring up the steppers to a cheap controller board and playing with axis commands to control them? That's the first step. Then put one of those RS485s in place on a secondary serial and figure out how you're gonna transmit control commands from whatever the control board is. The lights/relays/servos are pretty much step by step from there. Not sure you need a "port" exactly.
