I am involved in a project on GitHub that is not mine. Nevertheless, my team added me to the project as author.
On Careers 2.0, I am only able to add project I created (so within my "namespace"), or project of other I forked.
I don't know how far you track users and their project, but I think it could be fair to be able to link on a team project where the user is the author but not the owner.

owns the repository.
