just had a look on opensoundcontrol.org and found this very interesting iPhone/iPod application: TouchOSC

I can imagine that an interactive iPhone control of Ventuz could be an eye catching gimmick for you customers!
Ventuz controlled by your iPhone
Nice! Thx for the info.
You might also check out mrmr for the iPhone. Very customizable alternative with support for the accelerometer.
