All I can say is OMG....
The guys at Gamestring have developed software that allows you to stream a game from your computer straight to your mobile phone.
Click here to see the video!
I think you can stream any game from your PC, not just WoW.
I'll be signing up for the beta and trying this out, if it will work from my Palm Pre. Also, I'm getting an iPad for Christmas, so it would be soooo sweet it I could stream it there to!
I'll let you know when I find out more. In the meanwhile, enjoy the video, and dream of playing WoW EVERYWHERE!
The beta comes out in 45 days. I can't wait!
Update Jan 29, 2011: the beta page says its still 46 days till release. I guess they pushed it back.
