Until fairly recently, Google Code only supported Subversion code control publicly and Mercurial had to be specifically requested but now, Mercurial or Subversion can be used. Since I am using Mercurial to manage my branch of subprocess, this will make getting feedback on my code from the community much easier thanks to the large number of review features available.
As I was filling out the form to create a code repository, I ran into the issue of code licensing: Python has it's own unique license, the Python License, which is considered compatible with GPL according to the Free Software Foundation. Most of the code I am using comes from activestate.com and as such falls under an MIT license. After contacting the Python-Dev list, I am still at a bit of loss on selecting a license for the Google Code project and what impact the different licenses will have on being able to get my code pushed into the Python core.
