In a couple of the sessions I thought it would be great if BBB had some function like airplay on the Apple TV - that would allow presenters to open a website / youtube video / media on the participant's computer, but it would be the participant's computer that directly connected to the resource.
This would be good to enable a good experience of video / media without relying on the presenter's bandwidth, although not everybody would be in-sync.
Presenters: would this have been helpful? Being able to cast video / media to participant's computers?
Just a thought.
