I'd suggest against that from a safety standpoint (no backups), but what 
you _can_ do is to upload only the objects I don't have. 

This actually works - I already synced several weeks ago with Paul 
Mackerras, who had made his ppc64 git thing contain only the objects that 
I didn't have.

In other words, if you have my tree pointed to by
GIT_ALTERNATE_OBJECT_DIRECTORIES, and you populate your tree only with new
files, you can actually upload that small "sparsely populated" tree as-is
(without any of the objects that came from my tree), and I should be able
to pull it as-is.

Well, at least with rsync. I think my git "pack" send/receive thing might
be unhappy about a partial tree, but that's something I can fix, so if
this makes it easier for people (you can create a totally new tre _really_ 
cheaply and also upload it and move it around very cheaply), then I'm ok 
with pulling from partial repositories, and I have indeed already done so 
in the past.

Btw, if people start doing this, then I really think we want a 
".git/config" file, so that you can have different alternate object 
directories for different git directories without having to remember to 
set the environment variables all the time.
