Lately I’ve been getting alot of questions about an embeddable hangout on your personal/company site. While there’s not currently a way to do this through the google platform. There is a way to do this through some clever albeit inconvenient hack.
Get Live Stream Procaster (http://www.livestream.com/platform/procaster)
Stream your Desktop.
Get the embed code from the procaster screen and embed it on your site.
I know its a pain in the arse. But for now, it’s what we have to work with. It’s a bit delayed as well and users will only be able to spectate the hangout, they must join to participate.
