I was recently emailing with a former client, who told me that rather than buying a full-fledged CMS, they had purchased a smaller system they call a "page update tool." I'm a little surprised, I guess, but not entirely. And I imagine that the folks who will be using the tool might be pleased about it.
With a completely decentralized publishing model, this organization probably can't do more than enable folks to reuse their own content -- and even that might be in a future phase. If this tool gives the central IT group the time to think through the bigger-picture issues, it's money well spent.
