Martin's keynote was on live at 5:00 am my time so I just watched it and was disappointed that his screen share of feature in 2.5 were not recorded. This was a problem with the Sloodle presentation also. If you can't watch a live presentation you can miss important parts.
The current version of BigBlueButton does not support playback of desktop sharing.
However, putting on my Blindside Networks hat, we're going to work on manually converting all the recordings into videos -- with the desktop sharing -- so the iMoot community will have a full recording.
It will take us some time, but we'll get them to you. You can expect updates from the good folks at Pukuni (and likely a post to these forums) when the recordings are available.
Thanks Fred, I am looking forward to sharing presentations with colleagues.
