Haha, I have a small suggestion/request.

I don't think you should sell this script off. I think it has a lot of potential, but should be kept to someone who can develop and maintain it (and if the day comes when you want to move on, pass it along to someone who will keep it alive).

Releasing it for free (while certainly a better idea to people such as myself who are annoyed with/upset by the surge of money-whores to filesharing) is also just going to lead to too many sites not providing people with anything special.
