Speaker choice is a start....

I love the fact that I can have the alert sounds come out of my Cube's USB speakers, while all the other audio goes through soundsticks. It allows me to leave the volume way up even when my family is in the room, which cannot be avoided in my house. However, I would like to be able to use more than one set of USB speakers for sound playback.
With my setup, I should be able to choose all three USB audio-out options (Speakers, SoundSticks, iVoice). I understand that not many people have multiple sets of USB speakers, so maybe if you included the Audio-out jack in the list. If that takes more time, do the USB part first, then work on the non-USB stuff for later, and make it a choice: "the USB (pick any combination of the choices listed) Audio out or the standard audio-out".
