Adding a donation option for the app which a user downloads from the Software Center (if that project accepts donations). The donation will go to the developers of the project.
By this way, more people will be tempted to donate, because it would be easy and fast (you wouldn't have to search the develoeprs of that app online) and at the same time developers will be more motiveted to improve their software.
An example of an implementation of this is a second button (it could be a "Donate" button) near the "Install" button.
