How to pay your rent with your open source project
I asked this on HN a few days back.<p>I open sourced a library and its become heavily used by some of the largest enterprises who make lot of money using that library as one of many.<p>It takes a lot of my time to keep it updated so I would like to be compensated some how for the time it takes me away from my family<p>Even though its used by small and medium businesses I would like only the largest businesses to pay for it.<p>So how do I keep it open source as well as have the largest business pay for it? Any examples of open sourced applications doing the same?
