I waited. I waited. And...I waited. Finally Apple ships a wireless bridge to play anything from my G4 Cube Server in any room. Thank you Apple. Thank you. Oh yeah...and this also means that I have Xbox online or Nintendo Online access in any room because it has an ethernet and USB out. Thank you again Apple.
