The JesterML (
http://www.zero88.com/en/products/2/89) and JesterTL (
http://www.zero88.com/en/products/2/94) desks from Zero 88 include RDM functionality to discover and patch moving lights, without needing a fixture library. The fixture personality and DMX address can be remotely set from the desk, so no need for a ladder or any RDM tools on your laptop. Plug and play.
This was demonstrated at PLASA 2009 and can also be seen at LDI 2009.
