Tried it out -- shows the user's cursor fine in my experience.

  Cool. They could just give their testers instructions to use the cursor as a pointer to where they're looking. Or you could put that in your instructions to them. It's a decent enough proxy for eye movements any ways.

    Have you seen footage from an eye tracking session? A user can't explain or point his mouse to where he is looking. The eyes move quickly and somewhat unconsciously.
