From what I read about InDesign Server it sounds like an amazing product, but what I see by way of evidence are two case studies on the Adobe site (which feature the words 'CS3' and '2007' respectively) and a developer forum with 24 members and most posts unanswered.
So tell me, are you guys making ID Server do amazing things? Is it as awesome as Adobe is trying to make it out, or does it have a way to go yet?
That does look pretty cool. It'd make a better case study than the projects Adobe have on their site promoting IDS!
