Any Update on RDMNet or Artnet 4 Support?

I recently bought a Lumen Radio Stardust 8 universe CRMX transmitter. I would like to be able to use RDM with it from my ETC Nomad but it only has one ethernet input. I assume I can’t use RDM unless Lumen Radio and ETC both support RDMNET or ETC starts to support Artnet 4. Any updates on when either of these things might happen, if ever?
