You know how slow that would make these systems? Not to mention they will be pretty cheap hardware in the first place. So it would slow everything to a crawl if the complete contents of the hard drive were being constantly probed.
Not to mention VMware could easily overcome that. I just open up all my information in the Host OS, then virtualize the test. BAM, no screenshots, and no footprint.
