Hum, I guess I'm just missing something and prepare to get flamed, but
wouldn't you want that one to be bare? Otherwise, the other clones won't
see all of the original repo's branches, right?

Maybe even better:

mkdir local-mirror
cd local-mirror
git --bare init
git remote add -f --mirror origin <central-repo-over-network>

A cronjob (or whatever) could keep the local mirror up-to-date and the
other repos can fetch from there. Pushing would need to go to a
different remote then though.. Humm... Maybe not worth the trouble for a
bit of additional object sharing.
