Today Apple made some upgrades to its web-based version of the iWork suite that are more suited for those working in large teams. The number of people that can collaborate on a single document has been doubled to 100, and the maximum storage size for files and docs has also been increased.
Pages, Numbers, and Keynote can all make 2D and interactive charts in iWork for iCloud that can be exported to as ePub inserts for iBooks.
Not only did Apple beef up the number of people on a team that can work on a doc, its also increased supported Doc size to 1GB and will let you use images up to 10MB in any of the apps.
Other smaller additions, like object overlaying and chart formatting, show Apple is getting serious about targeting the enterprise demographic with pro-friendly features. Also added was the ability to show/hide slide numbers in Keynote, alternating row colors in tables in Numbers and inserting and editing inline tables in Pages.
iWork for iCloud is accessible for free in a browser to anyone with an Apple ID. Documents are synced between the web and native iOS/OS X apps via iCloud.
