that's a pretty cool idea. i think i like it even better than my method. I make a lot of hydraulic lines for fullsize aircraft, I think i could make something like that out of some aluminum tubing that would be lighter (and best of all... free). might even be able to rig some kind of pulley or even an eye screw to anchor them to the ceiling so that all it would take is letting the rope go a bit and they would be delivered into your hands.

thanks for the idea.
