Demoware Demoware is software to recommend a commercial product. An example. A company develops a database manager in order to control the expenditure. Of course this company wants to show the world how perfect this is. On the other hand, the company doesn't want to distribute the program for free. Demoware is a fine alternative then. It's a version of the program that works for, let's say, only a month. Demoware is in copyright and it is the editor who controls the ditribution of it. Most of the time it is for free but it is clearly different from Public Domain. You are not allowed to change it and it is not a complete program like Freeware. Demoware is a nice alternative. A negative side of it: you have a good idea about your program, but you are not able to really know your program until you've bought it.
