I've checked out binpress a few times before and they do have some interesting stuff. I say its more like a source code marketplace, which makes it easy for code authors to sell small utilities and libraries at no or low cost. I hope they succeed and become more popular, since sometimes it is very difficult to find easy to license source code.
I've been looking for a service like this for my Open Source project. We started out wanting to make this a business. I hope your idea takes off and I will browse around your site to figure out how to submit my project
Sure it can, but the donations need to be bigger, then you can quit your job and get a new job in Open-Source.
But that can lead to financial troubles if the donations stop...
I always wonder: Why not try to sell Open-Source-Software. For example The Gimp, sell it via the Ubuntu Software-Center, maintain the current version, maybe pack it with some great plugins and done. I am sure there are quite a few people willing to pay for that service.<p>Gimp is the perfect example in my oppinion, because it's such a great project without decent funding. Imagine what the could achieve with better funding.
