	We'll just have to let that one pass, untouched.

	Best inflatable building I saw was at some alternative
	housing thingy at OSU last year.  Somewhere in southern
	Asia they set a ver large bladder on the ground, arranged
	a large body of rebar netting on it, covered with about 6 
	inches of concrete and blew the	sucker up.  

	Instant conflatable concrete dome building.  It was very cool.
