That's actually very nice. There have been posts up here to find the changes as well as who made those changes. I'd keep playing around with it and think about submitting that for an article. There are requests for something like this often enough that I think it would be very beneficial for the community. Generally they seem to always want to know who which is the biggest benefit to using the trace file. The disadvantage that I got burned on with it once is if the instance gets hit with a ton of things that go into the trace, it can roll over before you capture it. So make sure you run the job often enough - I do now 🙂
