export .epub to editing tools on Mac
I'm not aware of any way to export things from the iBooks app. How do you plan to do that?

Connect iPad with iTunes Mac and copy the book to Mac. Then import it into Sigil (an open-source epub editor) http://code.google.com/p/sigil/.
In Sigil, edit whatever part I need. Then export to iTunes again and sync with iPad connected.
After this, the book no longer belong to the iCloud, but treated as ordinary epub imported into iPad.
