Phil, that sounds like an interesting workaround. It may be possible to edit the files in the SSISDB so that they show as a system database, but as it shows as a "User" database normally, I don't know that this would be ideal. I like the idea of having a separate project to store these and can see the usefulness of running in Synchronized mode for much of this.

I appreciate the original article as well - much food for thought there and some good ideas for future development efforts.
