I'll report further as I come across any stumbling blocks; but here

The submodule support requires the latest version of git right?  That's
going to cause trouble for people running different versions of git
(I've already experienced it in my own limited way - I had to upgrade
all the copies of git I have on my various computers before fetching
and pushing would work).  If the repository contains a submodule
reference it effectively becomes inaccessible by a version of git
without submodule support.

I think that we might be able to avoid that problem though - am I right
in thinking that the problem is that all the tools need teaching not to
follow the gitlink object because that hash doesn't exist in _this_
tree it is a reference to a commit in another tree.

Wouldn't it be better if the gitlink reference pointed at an object in
this tree which in turn referred to the submodule commit?  That way the
old versions of git would still work with submodule objects in the
repository because they would just see submodules as pointing at a
blob.

if you need to teach your version of git to accept this object that then points 
to the new tree don't you have to upgrade it to a version that does this? at 
that pont you could just upgrade to a version that supports them the current 
way.
