And it would be called Topfloorien, right, Esty?
I would have thought of Aragorn more as a secret agent type in a futuristic LotR instead of a bum. A shady secret agent type to begin with, closer to Jason Bourne than James Bond, and the hobbits wouldn't be altogether sure of who he works for at first.
Legolas and the other Elves would be martial arts masters as well as good shots with the bow, and would wear tight leather and shades, of course.
Hobbits would be a bit lost in a futuristic setting, don't you think? Everything that makes them "hobbity" is rooted in their down to earth, agricultural society and habits. So perhaps, in a futuristic setting, hobbits are the ones who maintain wildlife preserves or farms to ensure that the world doesn't become one big metropolis (like so many futuristic tales seem to depict....) Though, I can see them being into genetic engineering of foods. Giant pumpkins and the like....
