And no, it doesn't really work well if you want to use the speakers. It doesn't dampen the volume much, but it will muffle the sound quality. If playing music while docked is important to you, you are probably better off with the Sendstation Dock Extender in conjunction with an Apple docking station.
Couldn't you mill a slick horizontal groove in the front that went through to the docking well? If done nicely, I don't think it would detract from the look of the dock. Could even be shaped with rounded ends somewhat like the volume slider or progress bar on an iPhone.
Just a thought...I'd buy one!
