You might be able to pull this off using relative submodule URLs. If the 
submodule URLs in .gitmodules are relative (i.e. ../foo.git or 
similar), they will be resolved to absolute URLs using the origin URL 
of the super-repo. I.e. if you cloned the super-repo from 
git://github.com/x/mymodule.git, the ../foo.git submodule will be 
cloned from git://github.com/x/foo.git, and if you cloned from 
git@github.com:x/mymodule.git, the submodule will be cloned from 
git@github.com:x/foo.git.

Hope this helps,


Have fun! :)
