Kudos to the developers, but really, it looks like a piece of military or ham gear with heat sink fins on three sides of the case. I'm assuming that operating one of these in hostile territory is asking for trouble -- like a swat team through your door. Couldn't they have made it look like a boom box or really almost anything else that looks less incriminating?.
Other points the article didn't mention -- output power (probably illegal if over 100mW?)
Also, isn't it easy to locate a transmitter with some minimal sleuthing gear, like a dipole antenna?
