For many software developers writing code is a passion. However, many have been displaced due to the rampant outsourcing of their jobs to overseas competition. this is truly sad, however it could be an opportunity for those same developers to partake in the rapidly growing arena of after market software development.One of the most popular ways to make money off of this application is to develop your own custom modules and skins and then resell them either on your own website or the defacto standard website Snowcovered.com. The benefit of using snowcovered.com is that they handle all the details of selling your product so you do not have to worry about it. The after market for this particular open source application is huge!

The second open source application where it is possible to make some residual income is the ever so popular Firefox web browser. You can see examples of this by doing a simple Google search to see what extensions are possible. While some chose to give their software away some do sell their plugins for a modest fee. This seems only fair as the developer most likely devoted some of their free time in order to build the tool and should be properly compensated for it.
