Simultaneous/Real-Time Collaboration and editing

Hi,
I like everything about zoho except....

1. we have a 50-page presentation. If I make a change, though it shows up on the other's screens once they look for it, they do not move to that point in the doc automatically/their cursors does not move to where the change was made.
Is there a way to make this happen?
To be clear: I am on p 20 and make a change, someone else is on p 1. I have to tell them to go to p 20 in order for them to see that a change has been made. I would like it if ALL the docs stayed on the same page as changes are made. And for all the docs to change pages as one person flips through them. This would be real "real time."

2. This is a bit more involved, but it would be extremely helpful if at least one person (more = better) could have a visible cursor.  There is a constant need to point something out in a doc (we have charts, need to show a specific point on a graph) and there is no way at the moment to show this visually.

Any chance on either of these?
