There are lots of ways you can tackle this. If the devices are normally going to be used with your own controller then you can easily do this with a Manufacturer-specific PID in RDM.

If it is a case where you typically are going to be relying on someone else's controller, then doing it through plain DMX might make the most sense. You could look at the individual channels and do either an LTP or HTP merge in your device between DMX and the local fader to determine whether the controller or the device has control. You could also use another channel in DMX that the controller can wiggle to take or release control over the device as well.
