Check this shit out, if you install an x10 video reciever in your car and hook it up to a little tv, you can drive around and see whats happening on other peoples x10's...
It seems the x10 video transmitters can transmit pretty far making them accessible to anyone in the nearby area...
New niche perhaps?
