This is in fact a great way of doing it. You don't need a full blown computer. Any small microcontroller will be able to handle the serial input and react in a certain way. Over here in Canada anyways, some PIC micros are less than $1 each! And they are so low power that it could probably run off the headphone jack (i.e in a stereo headphone jack, the left could be the serial signal, and the right could be constant on at max volume which, if I understand, would be around + 3 volts.)
