I know of one example where this kind of integration is actually in place and properly utilized. It's a pretty big newspaper. The integration is provided by a publishing system called K4.
Admittedly, very few publications would employ similar systems here. Because they're complex to set up, expensive, and not easy to pirate (I don't think many small publications paid for their copies of InDesign/PageMaker), because there's inertia and fear of losing their jobs among the staff (not many young forward-thinking professionals in print nowadays), etc. Not sure how things are US, though.
