Really MAC filtering is only barely useful as the most basic of
management tools. e.g. You have a video game or mobile phone that
automatically tries to log into a nearby network, and it's a pain to
configure (or you can't). So you blacklist it, and have your net ignore
it. But that can only work if whoever uses those devices doesn't
reconfigure them to counteract your blacklist.
Another possible application is if you have a number of devices in a
department and you want to revoke access for one for some reason, but
you don't want to change passwords every time you do this, so you can
temporarily disable access until the next time you update
passwords/encryption keys.
