That's fine, I was only using the proxy object to allow additional

always be better to use a proxy object otherwise you have an error in
the tree object, because it will refer to an object that does not
exist.  The proxy object is allowed to refer to objects that don't
exist because it's not a tree object.

It is exactly the aim of my implementation to not have any reference to
something that is not accessible in the supermodule repository.

Is that commit in the submodule or the supermodule?

Well, logically that commit belongs to the submodule and is referenced
by the tree in the supermodule.
Phyisically it is stored in the projects object database which is
shared between the supermodule and all submodules (at least in my
implementation).

Hmmm, "shared"?  It must still be in the submodule physically though,
and presumably the supermodule uses alternatives to get access to it?
Otherwise the submodule will be impossible to separate from the
supermodule.

Yes, you can't separate it my just moving it out of the supermodule,
but you can always clone the submodule alone.

Okay.  I think I'm still a bit lost then.  I suppose I'll wait for your
patches to understand.

have a look at http://git.admingilde.org/tali/git.git/module2.
If you want to try it out, have a look at t/t7500-submodule.sh on how to
create submodules.
