one possible solution:
    - get an unused computer
    - get 4-6 cheap sound cards
    - combine their outputs with a super-trivial mixer: http://www.tkk.fi/Misc/Electronics/circuits/linesum.html


        As long as the soundcards retain their mixer settings when the power is off, this should
        result in a fairly brain-dead mixer, whose volume levels can be modified by software as
        needed (over the network, or automatically, or whatnot).


        If you wanted to use only 2 or 3 sound cards, you could use this:

        Cut it in half, wire each half up to a stereo input thingy...

        And connect that to the CD-ROM and aux-in line-level connectors
