Ethernet switch?

Okay, lemme explain what I'm looking for.  In my dorm at school we use wired connections and have to pay for service per computer (per MAC address I believe).  I want to hook up both my computer and my PS3 without having to pay for both.  The way people got around it last year was by giving their game system the same IP and MAC and all that so that the schools connections thought it was the same, and that worked, but you had to disconnect your computer and connect your game system.  That'll work, but having to disconnect my computer and connect my PS3 could be a pain in the butt depending on how my room is arranged.  So I'm look for a switch, not a hub or a router, but a switcher that I can basically hit a button and switch between the computer and the PS3.  Anyone know where I could get one?

I don't think there is such a thing.  What you could do is pick up a cheap router/firewall (it doesn't need to have wireless) and program the external interface's MAC address to be the same as the one on your PC, or at least the one the school has listed for you.  Then you could plug in whatever you wanted behind it.  

You may need to change the MAC address on your PC afterwards, but that isn't too hard.  It can often be done right in Windows.
