Demoware is commercial software released by way of a free download in a version which is limited in one (or more) of the following ways:
Remains functional for a set number of days from installation.
May only be launched a set number of times.
Is limited to a set number of "days of use".
Program execution terminates after a set time period (typically between 5 and 60 minutes).
In addition, the software hides code somewhere on the computer system (in Microsoft Windows, somewhere in the registry) that prevents removal and re-installation of the demo in an attempt to reset the trial period. Once the trial period is complete, the user must either uninstall the software or purchase a registration code.

One of the advantages is what I'll call "demoware" -- the ability to demonstrate your product or service using the Internet.
By using the ASP model as demoware, a company can show off all it can do for prospects without having to worry about expensive mailers, on-site demonstrations or other expensive sales-oriented processes.
A key ingredient in implementing demoware is to be entirely committed to it.
