Although this technology doesn't seem like too large of a leap from our current "bugging" technologies, I think that this stuff is too powerful to
be trusted in the hands of any government, or anyone else for that matter.
Being powered by the electromagnetic energy in the atmosphere, "they" can literally place this stuff anywhere they want, and use it on anyone they
want, without worrying about the limitations of batteries hindering their "investigations into our lives".
Additionally, the nano-technology itself has horrible implications. Scary stuff, if you ask me...
