I have commited some updates to my Android Tools library on github. I've merged a fork by ohhorob that allowed you to set a custom width for your pages. I have also improved the way it handles layered touch events, and added support for vertically scrolling child views.
Documentation is in the same place: jasonfry.co.uk/android/tools/doc
