PacketMover: The Next-Gen People Mover
Check this out. While Microsoft may not do it, it could provide a cool thing for Tomorrowland, if done correctly. Each 'packet transporter', has a selectable destination, and like a mini-monorail, will switch and move itself to it's requested destination, where it will then either pick up new passengers, or go to a station where more passengers exist.
If done in a TL like-sence, you could do the traditional loop of TL, or stations could be set up to drop off passengers. A quite futureistic thing. :)
