iPad 2 with OS 4.3.0 > Camera Connection Kit > DACmini was tested tonight. No powered hub needed.
IT DEFINITELY WORKS, and iTunes on iPad2 shows that it's connected the the CEntrance DACmini in the spot where a volume control would normally show up. And it sounds very good with my LCD-2.
Also tried DACmini with iPad 1 and iOS 4.2.1 (jailbroken but with no special audio software installed) - this also works fine with DACmini and no powered hub. Sounds great just like the iPad 2 that I first tested.
