I do this in Ardour but with midi. I use an old Digitech RP10 guitar fx
processor with midi capabilities. I can use program change data (either
0 up to 127) and if I assign midi to a fader, it sees it as a level. So
127 = loudest and 0 = off. Not the intent of PC midi but works anyway.
There are cheap midi foot controllers out there. I use the volume pedal
on CC 10 and assign to one fader in the Ardour mixer for live use.

Then i suppose you can use std file processing in perl [i dont use perl, but i heard it's rather complete :)]. The last thing you need is a file player which can be remote controlled. Either just launch aplay processes from the perl script, or use xmms remote controlling for example..
