There are a lot of comments on it. Some point to closer cooperation between the two agencies and possibly some sofware support for such cooperation.
In the fall of 1991 there was the Infoshare project, trying to accomplish the same general objective. As things turned out, it failed, I failed. The history of the last 30 years suggests maybe I shouldn't feel too bad about failure because getting the two agencies together was more difficult than we realized then.
