For all those WWDC newbies out there like me: I called ADC and they told me that last year, all attendees (regardless of their ADC membership) received access to all sessions on ADC on iTunes. Apparently, Apple hasn't made any announcements of this kind this year, but figures it should work the same way. That means you can go check out that really cool core animation or OpenGL session without worrying too much about missing out on that cocoa bindings one you should have gone to.
