Clever!

This seems like the sort of thing which could be adapted for amateur/DIY use.

It seems like you just need some hardware, which could be manufactured cheaply and easily, air-tight fabric, and a way of joining those.

I get the industrial / military / etc. uses, but I find the concept of anyone being able to build a temporary, usable structure in a custom configuration for a few hundred bucks a lot more interesting.

Still air is also a pretty good insulator, so if this were enclosed, it'd be a pretty good shelter even in colder climates.
