I agree. I've put the question out on the D-Light forums to see if there are any plans on supporting DMX - I get referred to the same posting at planet christmas.. Very disappointing.
Alas I guess the only way to really support the D-light controllers, the LEs, and the 3 channel dmx controllers will be to bite the bullet and purchase LSP. There appears to be little to no hope that Aurora will support DMX in the near future along with the D-Light and LOR support it currently has. The beta version of Aurora that supported DMX (as seen in some folks displays for 2009) appears to be unaccessable to anyone that wasn't or isn't part of the chosen few.
Was hoping that D-Light might do much the same as LOR and support DMX. Figured that with the Open ACx16 by now there's be some level of firmware support.
