This is what we do at work and it works really well for us. The
possible downside (that you can't tie project1 and project2 to a
specific version of lib1 in their own repo) is not a real problem
in our experience, as the superproject ties the correct combination
together.

That is where this is handled now, but having a submodule refer to a
submodule outside of it as a dependency is an interesting thought. But
as that only matters at the moment you add project1 (and it won't compile
because ../lib1 is missing, which can easily handled by: "oh, then I have
to add lib1 as a submodule to the superproject too"), I'm not sure that
would be a huge improvement over just having a sane convention of where
to get lib1 from.
