Network adapter....

will this work?

I am wanting to have my computer and PS2 to share a phoneline connection at the same time. So if someone is using the 'puter to surf the web they can also go online with the PS2. I heard that if i put a ethernet card in my computer and run cat5 from the card to the ps2 that would work when my computer dials up. They would both share the internet, is that true? or will i need to setup a network? thanks
