Wouldn't a tether be against the rules? 3.m. says the competitor may not steer the flight-- a tether would steer away from a certain height. Also, it is "free flight". Perhaps a tether could be added to next year's rules?
I'm still going to vote. It would be totally awesome to see SO get something like this. I've got it set up on my phone as a text and then click through on FB. Still a bit of work to vote on the site. All of that takes less than a minute. It's worth a shot.
