The Official Google Blog has details on a nice improvement to the hangout function that I've been talking about recently. You can now broadcast live onto your G+ profile page, your YouTube channel and to any page that you can embed HTML code into. You can see how many viewers you have, and the session will be recorded for you so that you can keep it and make available to other people.

It's also going to be very useful if you're running a training course or induction session as well. I can see how it's going to be really useful. Here's a video that explains it quite neatly:
