I've been wanting to get my hands dirty in USB, but I think I'll make a 
RS232 version first since it will be faster to develop.  I like the idea 
of having the microcontroller watch for "trigger" IR signals for 
toggling the LED states and writing to the LCD.  The microcontroller 
could monitor the IR transmit data from the PC and intercept certain 
signals so that they aren't transmitted, then perform the action.  I 
took a quick glance at the UIRT2 protocol and it looks like this would 
be possible.  I haven't chosen UIRT2 as the way to go yet, it was just a 
suggestion from early on in this discussion and I need to start 
somewhere.  I should be able to simulate IR receiver data for each 
button press on the front panel so that they can be mapped to actions 
such as play, fast forward, rewind, pause, and stop in the LIRC config 
files.  This wouldn't require a custom LIRC driver either.  Thanks, 
everyone, for helping me plan this project out.  I'm still very open to 
ideas at this early stage of development, so keep the suggestions and 
comments coming!
