It was announced at DevCon that recordings of some sessions would be made available. It wasn't clear if they'd be made available to everyone or just attnedees. It also wasn't clear how the recordings were being made; most comments I heard was that it would be the speaker's audio plus the screen cast of the desktop.
I haven't seen anything in the Developer Forum about these so I can only assume they're not ready yet. Is this where they will be posted?
