The JavaOne presentations are out!
I don't think you have to sign up to see them. They did a pretty good job of looping the soundtrack back to the video capture of the screen. There are a few places where the animation is pretty tightly coupled to the speech where you can see the looping errors, but for the most part, it is pretty good.
You can see my presentation about the Working Ontologist here .
I haven't managed to find the transcript of the panel session yet.
