It's actually fairly simple. It could get hairy with more than a few

well.
You can set QoS rules somewhere. I've never done that but have a hard
need (teen and networked games WHILE watching netflix AND group skype
call).

Every time you stop a school, you will have to build a jail. What you
gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
