in reply to To Release or To Open-Source?

Essentially, this is up to the individual. If you think people will pay money for it, and you don't mind doing all the support work, then sell it. If you think the benefits of releasing it to the community (feed-back, improvements, etc) are better than monetary gain, then release it as open-source.
