Pear runtime is now open, Keet apk is coming, supposedly with the next major update. It's pretty clear from the way it operates that it's truly p2p tho. If I'm not online things don't propagate. I have to leave an instance running at home to seed my rooms. And everything tends to work better when there are more peers. But blind forwarding is also on the way, so media should propagate more reliably when that hits.
