Will work just fine. I used to do this at the house back in the day when i had dialup. You are just sharing internet, not corporate protocols. Internet is internet. The easiest (but not cheapest) way would just get a router. Routers have internal hardware firewalls and stuff that makes internet more secure and you can hardwire like 7 computers to it, even more if you use wireless. You shouldnt have a problem though, fine tuning the settings can get annoying though.
