Back in the day we dreamed about exchanging deliverables so we could stop reinventing the wheel and start standing on each other's shoulders. It's odd something so basic as a repository hadn't been established (I don't think competitive advantage explains it in our open community). There is a collection of links on the IAwiki, and now AIfIA has launched a set of deliverable tools. It kicks off with a handful of top-notch documents from Erin Malone at AOL, sanitized and ready for reuse, which I think makes them a bit more useful than your average deliverable. I hope others will step up and put their stones in the soup.
