Flutterby™! : Turtle Talk with Crush

Sometimes the Pixar folks are positively garrulous about what they're working on, sometimes they're pretty mum. Bill hasn't been saying much about what's been happening in shorts since Boundin' went to film, but I just got a hint about what he's up to: a new Epcot attraction Turtle Talk with Crush. Interesting about this:

It's here that the real magic begins. At first, most members of the audience seem to think that they're watching yet another movie. Until -- that is -- Crush begins calling on individual members of the audience. Saying things like "You. Little Dude in the third row. The one with the bright orange shell. How are you doing this fine morning? Are those your parental units seated directly to your left? You mom's a total babe."

So I need to corner him and ask: How dynamic is this? Someone back stage who sounds like Andrew Stanton? Or do they have enough recorded that they can get a few folks out of the audience by combining a few clips?
