I second the opinion that the D30 cannot do this.

Best idea would be renting a digital scan back which will
deliver exactly what you need without time loss.

But then.... if he can't really estimate for sure what his
D30 can do, he'll be probably not very trained in digital 
workflow.....  yes, medium format and external drum scan 
is best.

Not really. Reproduction setup, two 250 Ws flash heads with 
barn doors and/or honeycomb grids will do.

I beg to differ. The best reproduction results from standard
light formers. To even out illumination, you need room to
place the lights in a distance at least 1.5 times the width
of the object.

While Iris is a fascinating medium, I'd rather look into 
diavographies, that are absolutely lightfast, rasterless
and provide dead matte black.
