Forgive me for asking what's probably an old question, but my search brought up no results.

I'm hopefully picking up a 360 this weekend (come on in, tax refund!). I have an ethernet cable running to my room from my router across the house (it plugs into my PC), and I'm wondering if I can just buy a switch and share the connection between my PC and my 360. It'd be a real pain in the ass to run another cable.
