You might want to check out the Core Audio Engine (CAE) component of 
Rivendell.  Basically, a completely abstract audio file player and mixer, 
controlled by ASCII string commands sent via TCP/IP.  You can find the design 
document at:

At present, this supports JACK, ALSA (up to eight simultaneous devices) and 
AudioScience HPI.

You may also be interested in Rivendell itself, which already does many of 
these automation operations:
