I appreciate all the replies! But I might be misunderstood...

I want to be able to control my media player. Say I have a window box with all my movies, music, etc. I want to be able to browse the content with my n810, hit command to play the media, and have the computer launch program and play media. And than have further options to toggle full screen, pause, skip, etc. Not really stream media through to my n810....buuuttttt....
If I had my N810 mounted in my car, and able to automatically connect to a device (say maybe a phone, ipod, whatever) over bluetooth, locate audio, and have playback options. That would be awesome!
