You want a Time-Bomb where a User can choose to Detonate it by changing the date to a post-dated date and only works on 4 PC's around the world with additional encryption on your data in a MySQL database?

What are you trying to do? Making bombs explode is not really included with the .NET framework but you could look up some custom libraries?

There are 3rd-party libraries available to add the time-bomb functionality.

The only way you can restrict it to four PCs is to have the application "phone home" when the application is started. Of course, there's really no way to restrict the number of PCs if the user is especially savvy regarding the methods used to identify a PC, so you're going to have to have them "regsiter" with one of four allowed keys that are stored on a remote database server (that you control).

There are too many things to talk about to qualify this as a "quick answer".
