I would definitely give that a go, though maybe a safety line (for the first few goes at least) wouldn't go amiss. Wind and condensation sprang to my mind immediately and watching the video gave me vertigo which I don't get when I work at height - still I can't honestly predict what I'd experience at 1700 feet. You could just use a retractable steel line attached to the top of the various (3 I think) parts of the climb, or a Grigri on a rope. Steel could be made weather-proof as a permanent fixture though. Either way it don't waste no time clipping and unclipping on your way up. I was holding on to my chair just watching him on the external part. If he was working with the guys I work with, one of them would have been shaking the mast at the bottom for added enjoyment. The view would be worth it I think.

Funny thing about aluminium is its tendancy to fail suddenly when under tortion that exceeds its capacity to withstand... steel will bend and creak and groan for a good while before it fails, whereas aluminium will SNAP suddenly.
