I'm trying my best to remember (I have been out of the service for 10 years now) what we called the posts, but the camo netting that gets thrown over tanks, makeshift command centers, ect. have these posts that have "paddles" that hold up the netting. It would be perfect. Just pop a couple in there and it will hold the netting up. I bet if you could locate it, it would be cheaper than PVC or anything else. Completely mobile too. It is what I would do if I had a round run.
