You could check if you router slots are free. They proberbly are.
You could enfore a bandwith policy on you users. You could have a static
bandwith limitation with ipfw meaning that they can only have 25% or a
dynamic one maning they have 100% unleass they use it heavly 25%.
(meaning lag when someone just starts using p2p). I have written some
article about this on my website. I integrated the ipfw firewall
options.
