We try to be very clear about licensing: http://www.mongodb.org/display/DOCS/Licensing http://www.mongodb.org/display/DOCS/Licensing. Please let us know if there is something on that page that needs clarification. I would like to make it clear that users of MongoDB don't need to opensource their product, only their changes (if any) to the MongoDB server itself. The commercial license is mostly for companies that have strict (if misguided) "no AGPL" policies. Most users do not need it.
