Something like that. I saw that and I thought it would be a better container than a lens case. First, because of weight issues - I don't think it would have been comfortable carrying nearly 6 pounds around my waist. Second, because I didn't want a loose cable dangling from the lens case, that eventually would wear down and possibly damage the battery leads. And third, I would most likely use it in conjunction with a lightstand, and not so much on a monopod/boom with an assistant holding it.
I'm getting some aluminum pieces custom cut at a shop, so it will look nice and CNC'd
