Alright, I am in a dorm with 2 network outlets in each room, one for each person.
I have an xbox and Halo-2 is quite popular on the campus and by plugging the network cable into the xbox, we can play anybody on campus by System Link (as opposed to Xbox Live).
The problem is that it is a pain in the ass to have to unplug the cable from my computer each time.
I was trying to find a RJ-45 splitter to have both connected at the same time using the single RJ-45 port. I found this:

Unfortunately, there is no link to the actual product, but you click on 'Network Accessories' at the top and it is at the bottom of the list (about 20 items).
Thanks in advance for all help!
