It would be interesting to deploy a few of them in different places and check that they all see the same as well maybe.

That's a great idea. And since they're only $5 each (I think I spent $15 with the power shield), it's not a big deal.

Also did you do this as a belts and braces thing or is the system you are auditing particularly high security/risk in some way?

When I got here, most of the web sites were riddled with worms and trojans and spambots other bad stuff. One by one I just nuked them and started over. This was a deliberate isolation to keep an eye on things in case the sites or the dev machines ever got compromised.
