I recently discovered a parameter to pass to a google hangout uri to make it "on air": reference
I'm also wondering if I can pass any other parameters. I know that we have app_id, but I'm more interested to know if there are other parameters, such as being able to set the title or the hangout in advance, e.g.
https://plus.google.com/hangouts/_?hso=0&title=EdX%20SaaS%20Pairing
Because then I could direct people to https://plus.google.com/u/0/s/%23hangoutsonair%20EdX/hangouts and they could see all the on air hangouts associated with our MOOC. I did experimentally try passing title=, topic= and name= all to no immediate effect ...
I'd also love to know if there's a way to automatically start the live broadcast, or even better have the hangout be automatically associated with and published to our G+ pair programming community:

Many thanks in advance
