I had thought about putting the device like the pirate box tacit wifibandit has used into a briefcase or a large book.
Make the power to the device run through a contact switch that uses a magnet to trip. This would allow you to toggle the power on and off to the device so that if you thought you were being tracked, you could just power it down without drawing attention to yourself.
For instance the handle on the briefcase could be flipped over to one side to power it on and the other to turn the power off.
Inside a large purse you could just have a much button toggle switch to turn it on and off, just reach in and push the button.
These would be the devices that would host some actual info like the jwfacts.com site or the elders book etc,..
