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.

Have I oversimplified it in my head?
