The last three lines are added to my companies closed source Git repo. In this example the company repo references git://github.com/larsxschneider/git.git as submodule. This submodule in turn references another submodule with a URL "outside.com". This is the URL I want to rewrite. Do you think this could be useful to others as well?

Oh nice, I didn't know about "include". However, as mentioned to Stefan in this thread, I fear that our engineers will miss that. I would prefer a solution that does not need any additional setup. Therefore the suggestion to add rewrites in the .gitmodules file.
