I've been thinking this leash device for your cell phone would make a good male chastity wireless leash as well. It's supposed to go off when you go a certain distance from your cell phone to prevent leaving it behind, but I could see it being used to monitor a device wearer as well. http://www.youtube.com/user/theZommVideo
