Just popped off my Ipod Touch adapter from the universal dock and my Iphone 4 docks with the Griffin Reveal case. The Reveal case 30 pin connector cutout is very small and only fit the stock USB cable...with the universal dock's pass through 30 pin at the rear I can use any of my charging/syncing cables. I imagine a wide range of cases will dock using this set up since there is plenty of room on all sides and since it's all white it doesn't even look like anything is "missing" from the dock.
Just thought I'd share that since some of you may own the universal dock already
