What is the difference between Ad Hoc and Infrastructure gaming on the PSP? My initial understanding was that Ad Hoc is for local gaming using a single WAP. For example Wipeout supports up to 8players in Ad hoc mode. I also understood that Infrastructure mode is play to 'over the internet'. Im not sure which games support infrastructure (i think Ridge Racer), but that means to me you could connect to a player(s) through the 'Net. I only get my understanding because of how wireless gaming works on the XBOX. To play any of the games over the 'Net you put the WGA in Infrastructure mode. To play someone nearby without a system link cable use a WAP and WGA in Ad Hoc mode. Can anyone clear this up for me relating to the PSP? I would really like to go buy an Infrastructure supported game, pop it in, search for a game, join, and start competing against folks across the country... if that is possible right now. Thanks.
