Including the same project several times is indeed interesting. Maybe the
subprojects should be "light checkouts" (I believe something like this was
already discussed on the list sometime). Those would be .git dirs, that would
only have HEAD and pointer to another .git dir with everything else.

Well, even if they might share a lot of objects they might be included
for completely different reasons and so might need to work with
different communities (remote entries, branches, etc.).

So sharing objects makes sense, sharing the rest of .git is not
neccessary.

One of the final ideas for "lightweight checkout" was having in
.git/config the location of "true" $GIT_DIR (or parts of it: 
GIT_INDEX_FILE, GIT_OBJECT_DIRECTORY), and "shadowing" the rest
of "true $GIT_DIR" with what is present in .git. It means that
you can have .git/index and .git/HEAD, and if you don't find
appropriate .git/refs/heads/master file you look to "true $GIT_DIR".
