it's certainly possible technologically, end of the underlying players we use xine and VLC, both do this already. The only part that is missing is we don't have a button to do this in the user interface, and if you start the media in one room and move it to another, the media plug-in doesn't properly set everything up. so will not be a big deal to add this functionality, but we just haven't gotten around to it, and it hasn't been a big priority since nobody has really asked for its before you.
