Before we begin I need to explain two things.  This story is about two computer programs that when used together can be very damaging.  1) When I was going to high school Trojan Horses were popular.  A Trojan horse is a program one person puts on another person's computer to either gain control of it or to just watch.  The specific one I had in mind is one where when you "take control" of their computer" a window pops up that is basically an image of their desktop.  But it is interactive. You can do anything that the owner of the computer can do.

 2) The second program is the Timelock program. It can be found at this website: http://www.timelock.rules.it/ This program is too complex to explain it all here.  What it does is it takes an image and hides it for a period of time that the program's user determines.  The way this relates to chastity is that you put on your belt and lock it.  The you put the key some sort of lock box and you lock that box with a combination lock.  Only you don't know the combination.  You change it without looking and take a picture of it with a digital camera.  The picture is then loaded into the program and locked there for a defined period of time.  The combination lock is put on the lock box and you twist the dials without looking.  Congratualtions you're now totally helpless.  Timelock also has many features to tease you (like showing the user a false remaining time) or to randomize the amount of time the image will be kept hidden.  The MOST important feature of Timelock is that it can communicate with other people's Timelock program.  In short one user can make a setting and send it to another.  When the other user accepts the setting they are then at their whim.  Basically Cyber-keyholding.  Now on to the bread and butter
