iTunes on PandaBoard/Raspberry Pi or other single board computer Has anyone being able to get iTunes to run on a single board computer like PandaBoard or Raspberry Pi?

I would like to do this to build a low cost, low power-consuming media center. If one could bring iTunes to run on such a low cost single board computer, it could be utilized as a music/video server which could be controlled via Apple's Remote App on iOs devices (e.g. I could stream music to AirPlay speakers or videos to Apple TV). I would also be able to stream music/videos it to my iOS device or Mac when Home Sharing is activated.

So, is this possible? Is there such a computer that is fast enough to do video streaming, running iTunes, attach HDD? Or are they all too slow? Any other obstacles?
The primary obstacle to getting a full featured program like iTunes to work is running OS X on non Apple hardware and/or Windows on ARM. 

I do run ubuntu on a Beagle Black and it is suitable for music streaming and light video streaming using open source packages. Nothing I have found works as well as an AppleTV and iTunes Match for music streaming, though. The black CPU is dual core, but severely resource constrained so it can generally walk or chew gum but not both.
