You can distribute our plugin unlimitedly. The plugin works with specific 4D structure files only. For example if you have a 4D structure "MyApplication version 1.0", we will provide you a product key code and license key code for the plugin to work only with 4D structure files whose names begin with "MyApplication". This means that they are valid for a 4D structure "MyApplication version 2.0" as well as "MyApplication version 1.0".
