Here’s a cool video of an integration available from Paradiso Solutions (note that this has not been released on Moodle.org). The integration allows you to launch Hangouts directly from Moodle. The possibilities for tutoring, class discussions and other communication objectives are endless. If your school or organization uses Google Apps, this might be a great low cost addition to providing online students a way to connect with you outside of the classroom (regardless of their device).

This is very interesting and a very good idea for Moodle, can't wait to see it in action.
