i saw the tree dwellers on a documentary a year or so ago. if you cross polinate your nuttiest pocket protector wearing engineer with some serious greeny weeny and add just a touch of the unibomber... well, you've found yourself a tree pod person.
i do remember the issue of trees falling down being discussed. apparently the way that it is hung puts very little stress on any of the trees and each of the trees is in turn anchored for increased strength for protection again high winds. i don't remember all the details but it seemed convincing.
