A pure monitor and multiple streaming boxes. A master media player, and all other media player/cable boxes able to operate as a slave to the master. Any box can assume the role of master, but the master controls which channels I watch, not the the slaves. I want one remote control that lets me flick between all the channels and adjust the volume on the audio system, also a slave. And I can have many of them connected also.
If there is one thing I can't stand about the entertainment systems of today is the need to have 4 (my brother has 7) bloody remote controls. And having to set the TV to one input and watch a channel over there. Then switch to another channel on another entertainment device. Oh, and I want to be able to listen to a "CD" off an MP3 player while I watch the football on the monitor.
