I would like to watch VIDEO on PC, and sit down in my bed with headphones on, the distance is 4 meters, and i don't want any cables.

I was suggesting Bluetooth, because it looked really simple, for example I searched for devices on my Nokia 6300 it found my netbook, available services ... remote audio (or something like that). I clicked on it, ant thats it. Now all the audio for my dumbphone, goes from my netbook.
The way that people pushed N900 to do things is nothing like I ever seen, so i thought this could be a simple task for N900. (Even bluetooh dialup was made by community)
The problem with wifi I have AIRFOIL (google it) and the audio lags behind, and sometimes is choppy, bluetooth on the other hand was used for audio for a long time, and worked flawlessly.
Thanks for all the help guys
