Yes that's possible. You need to activate ICS(Internet Connection sharing), can be done through the network wizard(Not sure if that is the correct name I am not using an English XP version). If you come across problems doing that just google for Internet Connection sharing there are tons of tutorials. You also need to put your wireless card to ad-hoc mode so it connects to another wireless client instead of a router. The drawbacks of a solution like that are that of course your computer has to be on and that your computer can only have one connection for every wlan card at a time.
