Here's the hidden little quote that caught my eye from John Noonan, technical director of show control systems for Walt Disney Imagineering: "We have a new attraction coming in Anaheim that's going to use the same network technology."
My bet: It's California Adventure's Little Mermaid attraction. Imagine the coordination of moving vehicles with screens that change to enhance the show scenes. The "Under the Sea" section of Ariel's Adventure could make wonderful use of this: thousands of fish and sea creatures swirling about you behind audio-animatronics of the main characters.
But, this is only my guess. Maybe we'll hear more at the D23 convention. We can only hope.
