I have run bitbluebutton for our elearning/LMS company. It is a good tool for personalized learning with smaller audience and ideally built for Learning. However, you cannot use it effectively to run large webinars etc easily in 1 session. If you train class sizes of say 20-30 in 1 session, you can run BBB and it will do a decent job. With their HTML5 release couple of years ago, everything now runs on WebRTC for the most part and they also allow using TURN and STUN servers. THe caveat is that it requires dedicated servers to run with some minimum specs. You cannot run it in production on a virtualized VPS (you potentially could but they don't recommend).
