I've been looking at RS-232 controlled receivers for a while and just 
wish I could find one that wasn't so expensive.  I have been talking to 
one of my coworkers about designing our own 7.1 amp that takes spdif in 
and has both rs-232 and usb control support.  Then we could write a 
mythmixer module and control the levels independently.  We would also 
make it so the levels could be stored per channel (I have some channels 
that are noticeably louder than others).
