Unfortunately, it seems that this approach too may be a dead end. The
iosniffer driver appears to cause an immediate reboot (triple fault?) on
installing its hooks. Given the low-level nature of the crash, the
thought of tracking it down makes me shudder. If anyone else wants to
try installing the driver, it would be nice to have a second opinion. I
guess it's back to the virtualization approach.
