here is a link to a program that allows PSP owners to play multiplayer games via internet http://teamxlink.co.uk/ what the program basically does is to "trick" the psp into connecting with your wi-fi as another PSP when actually the airport is just acting as a bridge to the PSP gamers online. so far i've tried wipeout pure, ridge racer, and untold legends (some lag). have yet to try tiger woods. anyway the easiest set up for airport express card users is to detect and connect your airport cards and "pair" with your PSP then use ethernet cable to connect to the internet. here is another usefull link for mac set up http://www.scottydelicious.com/kaidosxtutorial.php anyway this program also works for xbox, ps2, game cube, aside from PSP.
