Joomla wrapper / bookmarking component

I'm looking for a modification / module for a Joomla 2.5 site relating to the wrapper/Iframe feature, in particular the ability for a user to bookmark the page inside the wrapper.
I have detailed the requirements below

1. I need a system whereby a registered user in Joomla, preferably 2.5, can view a third party website via the Wrapper / Iframe component and bookmark that website (so that next time they are logged in and viewing the Wrapper / Iframe, they can select the bookmarked webpage from their favourites).
The bookmarking feature must be linked to the user account and not their own browser.
In the bookmarking feature, I would like something similar to the My Favourite Pages module at http://demo.greatjoomla.com/) which will dislay when the user logs in.

I would also like the facility for the user to create folders in the bookmarks so that the bookmarks can be organised

2. Another feature I would like to incorporate with regards to the content of the wrapper/iframe is the facility for the user to add notes/comments regarding that particular page. Obviously the comments would only be readable by that user and would preferably be displayed in a window / module below the wrapper/iframe.

I suppose this feature could be incorporated into the bookmark module as a kind of description.

The user would also need to be able to edit/delete the comments/notes.


3. The facility to export/save as well as print the content of the wrapper / plus any comments.



So in summary I am after:

A favourites module / feature where users can bookmark pages within the wrapper (and create folders to organise bookmarks)
The facility for users to add notes/comments which will display when the bookmarked page is displayed.
For the user to be able to print the page - including the notes/comments
Possibly the facility to save/export the same (content and comments/notes)
