Me thinks this is a *feature* this patch removes (as I understand it it was
a major design decision that everything /inside/ a directory is controlled
by git).

Why? If you let submodules live outside the tree I don't see any reason why
regular files shouldn't live there too (Disclaimer: I d not think that would
be a good idea either ;-).

What you want looks like this:

-+- lib1    #registered as submodule of project1 *and* project2 but not here
 +- project1            # submodule of the superproject
 |  +- ../lib1
 +- project2            # submodule of the superproject
    +- ../lib1

You are opening a can of worms by having two different repos point to the same
submodule living in a third repo (which also happens to be their superproject
and must somehow ignore it). You'll have two SHA1s for a single submodule;
"git submodule foreach --recursive" will have interesting results too; and so
on. Not good.

What about solving that with a "ln -s ../lib1" in "project1" and "project2"
(you seem to need that for your build environment) and adding the submodule
"lib1" to the superproject just like "project1" and "project2"?
