ePub Format in iWork

I just read an interesting article about how the ne update to iWork (Apple's version of Office) will allow export to the ePub format, making it easy to use to create books that can have full functionality within iBooks. This could be quite useful if a school or class decided to use iPads for all students in the class. Instructors could easily create handouts as books that could have all the iBooks benefits mentioned in my earlier postings.
