An idea was thrown out the the world on Google+ (Koushik Dutta) for a root only android app store. A place for apps related to rooting your phone, or other mods, along with all the stuff that Google and Amazon have banned from their app stores.
I think it is a great idea. I would love to see this happen and would love to contribute however I can. Check out the post (at the below links) and give your own feedback.
