just been reading some interesting threads on several Apple forums, and it seems as though there are big things planned for Apple TV. It looks as though there may be apps available in the near future that will run on Apple TV. I was thinking of an orbiter app running on the thing, interfaced with the standard apple remote. Wouldn't that be cool, not to mention the tiny footprint of the things, and no-fuss installation. (3 cables; power, hdmi, lan)
I have no idea if its feasible, or how much work would need to be done to make it happen....just passing on my thoughts.
Also I believe that Dianemo can stream feeds directly to the apple tv already with their UPnP system, but perhaps TotallyMaxed can explain this better than I.
