Would your script only work at "push time", or would it also work at "commit time"? I'm not sure at what point he thinks he wants to enforce it. I don't think git yet knows the info your script is asking for at "commit time" (ie, pre-commit hook and its brethren), and by the time it does know it's too late to block the commit locally. Maybe it does know that inof at the point one of those "commit time" hooks runs. I haven't tried it.
