I don't know if this already exists and I'm just not aware of it but I'm interested in starting a commission dedicated to ensuring an acceptable level of security in open source applications. Basically 3 or so members of the group would go through a project's source code for review. If they find any security issues they would inform the author of their findings so that it can be corrected. If all members are satisified with the project and they feel the project meets acceptable security measures it will be awared a bronze star. If a program lasts for at least a year with no security issues or at least quick fixes it can be reviewed again with higher criteria and be awarded a silver star. If a project is out for at least 3 years and has shown exceptional security the project can be reviewed extensively and be awarded the gold star. These would be very rare. I don't care about whether I start this or someone else but I feel it could be highly beneficial. If the commission and awards get high praise due to high criteria it could be a good selling point for any software awarded and help push the idea of rock solid open source software.

i believe these kind of initiatives can be really good for the community... and i believe if you play your cards right you might even make a few bucks, who knows...
