I hadn't seen this thread back in January, but yeah, take my money. I'd love to do this!
With what must be very low capacity, it seems better suited for adventure/tourist areas like Pigeon Forge, Vegas, Niagara Falls, etc., than in a large park that already has a sky coaster or drop ride. Still, I hope this concept proves itself and we see more of these.
One last thought -- that railing could stand to be a little bit higher; I think walking around up there would scare me more than the rides.
