One thing I'm considering, at some point, is to start a cooperative-like business. This kind of enterprise is normally associated with manual labor, but I can't think of a reason why you couldn't have a tech coop. I actually think it would go hand in hand with the idea of more craftsmanship in software development (something I'm also in favor of), not to mention that it would greatly improve workers' rights (since the workers would also be the owners of the business).
