I've accomplished a similar setup to this stackoverflow challenge.
Except it seems to break the UIViewControllers, because they don't receive certain messages properly (eg. viewDidAppear)
Further research reveals that the solution rests in iOS5 by using some container UIViewControllers.
Has anyone accomplished this successfully with UIScrollView? I watched the WWDC2011 video on it and it's still confusing me on how I exactly replace my UIScrollView:subviews with full UIViewControllers. :/
