Stable permanent setup with MAX, DMX and DALI

Hi all,

I am working on a lighting installation with 9 chandeliers, that will be using 20 LED's each to create a dynamic lighting effect. At the moment I am at a prototyping stage, controlling one chandelier using MAX to generate the dynamic effect, and an ENTTEC DMXUSB Pro as a DMX interface.

The project will be a permanent lighting installation in a public space (vistor center/restaurant function). Hence the system will need to be stable and needs fool proof control. Aside from a simple computer interface in MAX, there is also a need to simply dim the light installation via the DALI system with which the general lighting in the building is also controlled. Hence I will also need the ability to receive DALI signal.

For this kind of installation, what kind of hardware would you recommend (and what would be the implications on the software side)? Is an ENTTEC DMXUSB Pro sufficient, or should I go with an Artnet interface? (or doesn't it make any difference in stability?)
Regarding DALI input to MAX - I am guessing the easiest way will be to use a DALI to DMX interface, to keep only one line of communication between MAX and the physical system (throught the DMX or Artnet interface). Do any of you have experience with receiving DALI protocol directly or via DMX? Anything I should take into account in that regard?

Anything else I need to consider for a permanent installation regarding hardware? In terms of programming I guess there will also be challenges, but that will be a separate thread when I get to that.
