You might find 'git new-workdir' from contrib/workdir to be helpful.
It lets you attach multiple working copies to a single set of objects
and refs.
There's a patch series to move that functionality into core git
through an option "git checkout --to=<directory>" that creates a
new workdir for an existing repository that is currently in the
pu ("proposed updates") branch.

It's possible to do, but we haven't written a nice UI for it yet.
(In other words, you can do this by cloning with --no-recurse-submodules
and manually creating the submodule workdir in the appropriate place.
Later calls to "git submodule update" will do the right thing.)
Thanks for a useful example,
Jonathan
