Using Porting Center, anyone can export a port as a WSI file and share that file accross the Web. Sure, you will need some knowledge in porting to start, however, with time and effort, you can become a Standalone WSI Developer.
Furthermore, it's also a port editor, and can also be used with any kind of Wineskin-based port, like CXSkin, CXZ and CXEx, export them as WSI files too, converting them to the most recent Wineskin Wrappers.
