I want so much to be in the business of selling my own traditional downloadable software, that I've thought about (in the absence of an idea) just putting together a do-nothing application with payment, installer, configuration dialogs, bug feedback - everything but a raison d'etre. The irony is in my day job I am developing a traditional downloadable Windows application which will come with an immediate user base. But although I have considerable discretion over the project, it isn't mine (in an intellectual property sense), and I'm not getting rich off it.
