I've looked a bit into how several PS3s could be linked together in a private LAN, and from what I read on teh interwebs, it seems to be possible with simple patch cables and a switch. (not that I've actually tried myself yet...)
However, I don't know if there's a way to play wipEout HD over LAN, since I don't see any LAN option in the game's menu itself. So my question to everyone (yes, that also includes you, SL people!) is: does anyone know how to create a multiplayer session in HD via LAN? Is it even possible? Has anyone even tried creating a PS3 LAN for any game at all?
Any help would be much appreciated, we only have until May 2009, Frankfurt to find a solution!
