As co-ordinator of the various LDI and PLASA RDM demonstrations, I can confirm that the interest in RDM is both serious, and growing rapidly.
ACN will not replace RDM, as in many situations, the multi-drop RS485 infrastructure in getting wires to devices is far superior to the star network required of 10BaseT or 100BaseT Ethernet systems.
ACN and RDM will be complimentary protocols - indeed at LDI this year we saw a prototype LX console talking ACN to an ACN/DMX/RDM gateway, and thus presenting directly at the console the existence of a simple RDM enabled device at the far end of a DMX cable run.
