I think using the hog/cattle panels, or remesh (concrete reinforcing welded wire), is a really good suggestion. I've wanted to get some cattle panels to use for vertical growing, but I tend to get paranoid about hauling stuff and can picture having the panels in the back of a pickup truck as per Ravencroft's description, hitting a bump and having them spring out and kill some poor passerby...
I did buy a 50-ft roll of remesh this year and have used part of it to arch over a steel hoop house frame to grow some gourds, cukes, etc. on this year. That roll is more than a little unruly, though, so I was pretty happy to survive that little project without needing any band-aids (or worse). Remesh can be bought in panels, however, I think 4x8', which would be much more manageable and easy to transport. The biggest drawback is that it does rust, so expect to be kind of a mess after dealing with it! At any rate, cattle panels and remesh are nearly self-supporting and really eliminate a lot of hassle with the framework.
