If you augment a shared page with private information, you make the
user vulnerable to clickjacking. The attacker, knowing the URL of the
shared page, directs an invisible frame to that page. The attacker
then tempts the user to click at the screen coordinates where the
private functionality will be added.
I suggest you make an account-like object that keeps track of all the
user's resources. When the user joins the application, they bookmark
their account object. This is the only bookmark they ever have to
create. All other pages can be found by navigating from their account
object. If you are worried about getting at the resource from a new
browser, you could implement a logon interface, or email the URL, etc.
