You could do that. Depending on how your DSL is set up, you could also just get a hub. In fact, if your DSL is set up in such a way so that your sole IP address is assigned to your PC, I'd suggest getting some sort of firewall/router device anyway, for network security's sake, and then you definitely can do what I suggest. In fact, most of those firewall/router jobs have a small hub built right in.
