Google has announced that Google Docs are now included in Hangouts on Google Plus. When in a Hangout, you just click on the new "Docs" button and you can add an existing document, upload a new one, and switch between and collaboratively edit multiple documents at once.
This is another great feature of Google+ Hangouts for education. Teachers and/or students can hold study groups, help sessions, or work on other projects using Docs in Hangouts.
