My only concern is that I wouldn't want just anyone to be able to choose my
mirrors as a default.  Let's say the new guy accidentally tells his 10,000
servers to hit our california mirror as their primary mirror, we'd be in trouble.

Summary: It should be up to the mirror maintainer to determine what traffic is
artificially steered to it, and he should only be only allowed to be steer
traffic from IPs under his direct control (AS).
