This is interesting. Even more, I would like a software publisher, to package open-source software with an installer for various platforms (mostly Windows/MacOS), set up a landing page, provide invoices/POs to companies that need it, deal with payment and refunds, and just give me a cut. Does anyone know a small company out there who does this?
