Re: Turning off computers wirelessly
I have no idea if this will work as I have not tried it, but there is a VNC application for the PSP (hacked PSP, of course). If it actually works, you could VNC (kind of like Remote Desktop) into your PC and just run Shutdown. This is all in theory, however.
But I'm trying, Ringo. I'm trying real hard... to be the Shepherd.
