I never did unfortunately, and due to other priorities I wasn't able to chase it up. I have just completed a major task that has taken all my time for the past few months, so I might be able to follow up on this with the security team again this week. I'll let you know how I go.
I really would like to get this out there as it works very very well and I'm actually quite proud of the modifications I made to make this work properly, but the decision is out of my hands unfortunately.
