Tom,
First of all as a still lenes the focus is focusing in reverse not cine direction. On the focus scale from 2 1/2 feet to infinty there is 1/8 inch of travel so if you want to focus at 5feet or 10 feet the focus travel is about 1/witness mark of travel.
There is no iris ring.
As a rehoused lens the focus is going in cine direction and the focus marks are expanded. In the pictures that you saw the focus roatation is 40 degrees of travel. Wth engraved marks 1ft 8" 2 feet 3feet 5 feet 10 feet and infinity. now we have gone a step farther we expanded the focus travel from 40 degrees of travel to 90+degrees not sure anywhere between 90 and 120 degrees. there is also an iris ring. The iris focus and zoom all have cine geared pitch. internally all the movements have been modified zoom bearings stainless steel cam followers etc. I hope this helps you to understand . Also you have the option of 105mm front or 110mm front.

These are all good features - if someone uses the lens in a cine style shooting environment - which is obviously the intended use for your re-housed lens.
But for the multitude of indies, who shoot in a hybrid style workflow, who do their own focusing by eye racking the lens barrel, where no AC or focus puller is involved, do mobile work where they need lightness (thus don't use a follow focus), and who use the Underdahl Nikon mount knob to control iris, none of the features you list are a necessity or major attraction.
I won't be buying your Ruby because me and my crews use the indie hybrid workflow I just described, which makes the most operational and fiscal sense for us - and the RED images we've been generating with the stock Nikon 14-24 have been stellar. We do a wide range of network and cable TV production, stock footage, some commercials, and a fair amount of high-end business media.
All this said, for those who do a more traditional cine-style field workflow with RED, use focus pullers and follow focus units, and want/need a real good wide cine zoom, I'm sure your Ruby will be great. The features of your lens seem excellent for that.
I think everyone simply needs to analyze what genres they usually shoot, the best crew and equipment for that, and then decide on their lens purchases accordingly.
To each their own according to their needs...
