You don't HAVE to have a router, but you do need something that can assign the PS3 an IP address (routing capability). Windows XP computers have a feature called ICS, which stands for Internet Connection Sharing. Your PC will need to have a spare Ethernet port open to use it, so if you are hard wired to your cable/DSL modem, you'll need another add-on Ethernet card installed.
Set up the Internet connection on the PC, and plug the PS3 into the other Ethernet port. Run the ICS wizard, and Windows will assign the PS3 an IP address and share the Internet connection with it.
So, there's your workaround. However, it's MUCH easier, and in everyone's best interest to have a router installed between your gear and the Internet. Routers have a lot of security features that help protect your stuff from bad people, and it makes sharing your web connection with other things on your network significantly easier. Besides, basic routers with wireless capability are pretty darn cheap anyway. Keep an eye out for sales and you'll probably be able to snag one for less than $25.
