There aren't any complex shipping chains.
Goods go china -&#62; Europe/US the only thing that goes back is waste.<p>I can't see this helping.
It costs more in a very price sensitive industry.
Rollup doors means it isn't going to be used for shipping anything  valuable or anything which then needs further onward shipping at the destination - are you going to have a truck full of DVD players going down the highway with canvas doors!<p>None of the existing handling systems is going to be able to deal with them, so you will need special cranes to load the collapsed ones - unless you load them inside regular containers.
