If anyone's interested in a XTension (Mac QuarkXPress 6.5) I knocked up in a bored moment that imports Photoshop color books as spot colors, drop me a line.
Edit: I neglected to say that I can produce PS color books from ICC named color profiles and InDesign swatches. I can even create ICC named color profiles too using measuring instruments.

It's an app I've been working on... some of you will know who for, I guess.
