Plex Media Center, a Mac and PC application, allows users to stream content wirelessly as long as they have it hooked up to their TV. The app underwent a name change and is currently referred to as Plex Home Theater versus Plex Media Center.
The only small issue with this announcement is the fact that the general public cannot download the updated version yet and the only users that can get it are paid PlexPass subscribers.
The concept is like Slingbox but features a much smoother UI. Furthermore, the selection is endless, and streaming to your Apple TV is a massive plus.
