It should be possible to comment on specific parts of the page. Like in www.invisionapp.com So it could be possible to discuss an artwork with my client. Like I'm doing with PDF-comments at the moment. But in this case I could reply and discuss more. (show more than one versions of one page would be excellent!)

Yes I need more collaboration tools too. (like features on Google Docs, Apple Pages…)
