I read this, and I can't help myself thinking: This would be such a non-issue if you had one _repository_ per-user. If they take too much space, set them up with "git clone --reference=<official-central>", so you automatically use alternates.

You would not hit the problem where two developers want to push onto the same branchname, too.
