Sounds interesting. I can see a potential usage in remote tutoring. Parents set up their kids, who don't understand something, and use it to speak to someone qualified (you could have pre-approved lists or groups of people). And by virtue of being google, it has a large potential audience. The potential for abuse would have to be carefully monitored/considered, of course.
