Ideally we could do this without session, but pragmatically we still need it, because of the inflexible routing system, and because of performance considerations. Example: The tree is lazy loaded via a generic URL (admin/pages/treeview). While we could add ?ID=<currentpage> to make the view (more or less) stateless, it would trigger a full tree reload on every tree navigation action. Instead, we assume that all "reachable" nodes are already cached, and simply mark a different one as current. For this to work, we need shared session state between CMS controllers. See http://open.silverstripe.org/ticket/7815 for detail.
