what is the difference between beo5 and beo6
Well, on the "hardware-side" it is just a backchannel for showing covers of cds on your Beo6 in combination with Beosound 5.
BUT what really thrills me is what will happen, once the protocol is "reverse-engineered".
You could integrate a Videoserver in your masterlink-system just by adding a piece of software on your Mac/PC (think of Linkplayer - with covers of available movies shown on your Beo6, or the actual temperature of all rooms in your house, or the picture of the webcam in front of your house shown on your Beo 6 when somebody rings at the door)
The possibilities are endless - and in opposite to your phone that is often not available as a remote when you leave, the Beo6 is always around where you have your living area!
