Thanks for the reply. I hadn't really thought of using VMs to create an additional layer of separation between me and tracking and profiling companies, mainly because running a VM on my bottom-of-the-line machine was a painful experience when I tried many years ago. I think I'll try that again once I've upgraded quite a bit.

At the moment I'm stuck with a bunch of other responsibilities, but when I get around to it, I'll drop you a message with any questions I have. Thanks again.
