Yes it is very possible to implement Auto-Addressing for DMX devices using RDM.

The first requirement is that the device actually supports RDM so that it can be discovered and have the address set for it.

In a nutshell it would work like this:

1. Discover the devices.
2. Send a GET_COMMAND : DEVICE_INFO. In the response for that message it will tell you how many DMX channels that device needs.
3. Send a SET_COMMAND : DMX_START_ADDRESS to set the DMX Starting Address value.
4. Since you know how many channels that device uses, you now know the next available Starting Address for the next device.
