The commercial software community that grew up around the Borland (now Embarcadero) Delphi development tool is a good language. This was a component-environment. Typically pay one price for the component and a higher price for the sources. Lots of commercial products that distributed source code. Delphi itself distributes source to the entire framework. Might be a good place to look at licenses. http://www.embarcadero.com/products/delphi http://www.embarcadero.com/products/delphi
