nano-summits over google+ hangouts

Hi All,

From what I've heard and saw it seemed like the google+ hangouts in

the rooms worked fairly well. (For the very small sample size of the people I've talked to)

I'm wondering/tempted to try out as an experiment on going single topic Multimedia sessions from time to time between Linaro Connects. Given that a focused single topic session would draw a smaller "crowd" the 9 person limitation I don't see as a big deal especially with carefully chosen topics.

Is this something that is even possible? I know the google+ hangout over the air is by "invite" only so it's important to know if their use might be available for more than just linaro connect.

Thanks!
