I just came across this link to an outdoor gear show debut of a new hammock from Exped. It's actually similar to something I've designed in my head many times, but never built due to some concerns I had about its practicality. My main concern is that the spider-web of lines linking the perpendicular hammock to the trees would become tangled easily. Still, it's a neat idea, and something similar might end up being the best way to make a true, proper two-person camping hammock.
