Agree it's great for small meetings (2-3 people). P2P without any server in between, works as good as your connection.

One thing that bugs me though is using it in Chrome in Mac. 50% of the times the microphone doesn't work and I have to kill coreaudiod and restart the session. I came to a point where I do it before I start a meeting just in case.

It's not appear.in problem though, it happens in Hangouts in Chrome as well
