Is it possible to call a locally installed ibook from a hyperlink? What about to a bookmarked page?

I have 2 questions..

1. Can I send a link via email that when launched will open an ibook that has already been downloaded to the bookshelf?

2. If question 1 is possible, can I take it a step further and call a bookmark, i.e. chapter 3.

Our company has it's own appstore and I want to send out links to sections of the ibooks using bookmarks or at the very least take them to the start of the ibook.

I don't need to give them a link to install the ibook as they already have it installed.

Any help would be much appreciated.

Chris.
