I want one of these things - bad

Got a cool press release from Maryland's Clark School of Engineering today (via Reuters) about a remote-controlled monocopter, or "Robotic Samara," which is based on the design of a maple seed. You know, those things that spiral to the ground, falling like they're only half-aware that gravity exists? There are lots of cool possible applications, with surveillance high among them, since they can hover in place and be launched from just about anywhere and are just about noiseless. Check out the demonstration video: It's not entirely clear to me why this is better than a helicopter, but I think it's basically just fewer moving parts. Either way, it's cool, and I want one. What do you think the MSRP on that baby is?
