That seems like a very expensive way to go camping, not to mention the additional trouble of climbing 4 trees to get it set up and having to navigate a ladder in the middle of the night when you want to go to the toilet. At least you are safe from bear attacks.
I get the feeling that the elegance of the design far outweighs any practical aspects of camping. If you are going to have 8 attachments, four at the top and four at the bottom why not make it cube shaped. I like spheres and domes as much as the next person but they aren't the most practical things, I guess the rain would run off it and the wind would blow around it better and you can't lose things in the corners.
