I scanned and searched, and didn't find anything previous on this topic. I've run across information on using a "darknet" in place of, or in addition to, an IDS or other network protections. The project is described in this link:

Has anyone set up and run one? What success have you had with it? Mostly, looking for some real-world validation that I can take to the rest of the crew at some point. The idea sounds good and may be a more "proactive" solution. I hate that word, but the concept is good.
