Interestingly, there is a standard not only for the format of a digital music
signal, but I was pleasantly surprised to learn (and see, at CES) that
there is also a standard for a fiber-optic connector, as used in connecting
CD's and R-DATs together (yep i know the sampling rates differ, but you
can go A/D and back in the R-DAT (i think) and you can hook R-DATs together).

There is even a preamp from Kenwood that has digital input (I don't know if
it has optical or RCA connector, or both) but I was told it goes D/A right
away (before any frequency domain processing).

The format standard, authored by Sony, I believe, includes a few "reserved"
fields which may be suitable or intended for information in the system you
describe, such as volume specification.
