From the developer:
As long as plugSHIELD is running, no one can plug and copy anything from your Mac.
While activated, plugSHIELD will shut down any plug & mount attempts from USB, firewire, memory card and other ports. Your mac will refuse to accept portable devices plugged into it, be it a USB flash drive, an SD card, or a firewire removable hard disk.
Also, as a bonus, you may give your iPod or other device a real quite power charge without iTunes pop out.
