Definitely cool, but I'm not going to take the time to assemble and disassemble that thing on the spot. If I ever decide to use totems, they'd have to be assembled in advance. Being able to transport them in a small case like that would be great, but if I didn't have room for preassembled totems in my minivan (and I don't), I could always carry them on the (roof top) luggage rack.
Yes it is a lot of extra work. But... I can have 4 of them plus 4 movers plus 24 uplights plus all my dj stuff plus my helper all packed in honda element. Something for something trade.
While this is true, there is something to be said for a solid welded truss. I don't know what the weight / load differences are, but there are some. In addition, time is money - so while you may save space, you won't save on setup / teardown time.
