Great question Emil !

It turn out that the Christie's DOES SUPPORT ARTNET !

We can control the follows parameters from Artnet .

ch 1 ) Shutter
ch 2 ) Lock / unlock Artnet
ch 3 ) video input
ch 4 ) channels ( it's a Christie's things to recal settings )
ch 5 ) Lens Vertical
ch 6 ) Lens Orizontal
ch 7 ) Focus
ch 8 ) Zoom
ch 9 ) Power
ch 10 ) NOT USED , but it's there

I've tried my self and it does work very well .
This allow me to use Video projectors with and without Orbital Heads and control it directly form the hog . What I had to buy is an Artnet DMX > ARTNET box .

It could be nice if king Richard could write a peace of software in the catalyst to control and store those directly from the catalyst software when it's used in stand alone mode .
