Very interesting. As far as hammock tents go, assuming it's good quality, this one is probably tops. I haven't seen anyone using a hammock tent in my part of the world, so I haven't had a chance to ask anyone first hand about them. They seem to be uber comfy, by the look of them.
The big drawback I see is that as a rule they require two stout trees within a certain range of distance from each other. I've camped in several places and can think of several more where this would absolutely be a no-go, because there would be nothing to secure it to. In some situations you could maybe string it between the roof racks of two vehicles, if you can convince your buddy to let you use his, but even that isn't always possible.
