arduino yun and DMXSerial2 or Artnet for RDM

i am planning a project for which i was hoping to implement wireless RMD/DMX communication.

DMXSerial2 offers RDM bi-directional communication. http://www.mathertel.de/Arduino/DMXShield.aspx

I am wondering now if this could be coupled with the Yun, or if it would be better to get the regular WIFI shield?

or would it be better to use the artnet node library with the yun wifi: http://www.deskontrol.net/blog/arduino-based-artnet-node-for-led-pixels/

It would be great to get RDM working since it is bi-directional, not like DMX.

thanks,stephan
