need help not getting busted for downloading

[deuces]

i'm in college and i live in the dorms, connected to the internet via a LAN cable. i download a lot of music on limewire and all sorts of things on bittorrent. one of my friends has gotten a letter about his downloading habbits from the school, threatening to take away his internet.

i have a theory that i could be safe by not connecting to their wireless network, which makes you register with the school. however, i am not sure this theory is valid.

does anyone know how i can keep my bad habbit without getting busted?
