Santa figures out what they want through all sorts of Big Brother techniques “…via a listening antenna that combines technologies currently used in cell phones and EKGs.” He also uses this information to determine the optimum route.
The toys are handled by nano-tech, with each toy created in each house. No more Santa’s workshop, I guess.
And all the toys (well, toy factories) are delivered through “relativity clouds,” where Santa can stretch the space/time continuum to deliver all the toys in short amount of time in our concept of time.
Of course, this is all possible because Santa and the elves are all much more educated in the principles like quantum physics. Or maybe Santa is just an alien with all this advanced knowledge…
