Software I'd Love to See Open Sourced (or at least have a public API)

I came across this ad while looking at the latest from the American Family Ass.
First I'd like to mention that it isn't free software (neither as in beer or speech) Second, it only runs on Windows so I'm shit out of luck (I guess I could try it under Virtual PC, but that is an exercise to be left to reader or until I get motivated to first load up my VPC image with porn and second see how well it works)
Anyway I would love to write some software that uses the API, I'd like to write two apps in particular. The first one would be a tool kit to clean your porn off a computer you are using. The second is that I'd like to write an app to help you find lost porn, if this tool is good at finding porn you could use it quickly access your porn collection, kind of like Spotlight for your dirty pictures.
