I have a Russound system in my house, with IR on each zone's keypad. This allows me to access all the sources in my HT's cabinet. I have a pronto in each room programmed with the titles of all the cd's in the megadisc changers so that all you have to do is select the title, and it starts playing. I ran Cat-5e cable for each keypad. There are enough pairs of wires in one cat-5e cable that I was able to add a paging system in each zone as well.
