Anyone ever use this? Would seem pretty sweet if it works well. I'm especially wanting to know about PSP access.

For those who dont know, this is a program that allows Xbox, PSP, PS@, and gamecubes the ability to play online. It essentially lets any game that is AD-Hoc only (on PSP) play like it has multiplayer built in.
