I had a similar experience a while back with my software, Mayan EDMS an open source paperless solution. Things I learned: You are better off going first after a copyright violation, then after a license violation. Pick a previously tested license, resist the urge to craft you own, we are not lawyers. As the code owner you also have the community behind you, use that.
Those do make Django awesome! :)
I myself use Fabric, Spinx and Pillow for almost every project. Django Nose is now in the list, the rest you mentioned are in the Awesome Python list at https://github.com/vinta/awesome-python, cheers!
