We just listened to an audio broadcast EdTechTalk, a community of educators interested in discussing and learning about the uses of educational technology. They covered BigBlueButton in EdTechWeekly #147. You can hear them talk about the product at about 29:00 minutes into their broadcast.
They were positive in our efforts to provide an integrated setup. They also correctly pointed out that we don't have record and playback in the system yet -- that's coming soon. Right now, we're focused on getting release 0.63 solid and finished. We've got plans for record and playback in the future, but we know from experience that we need to focus on the current release.
If 0.63 is good, then we'll have a solid base for adding record and playback in future iteration.
