Includes a plugin for 2.0 and a potential patch on 2.0 to add a new 
capability "edit_others_pages" that might interest you.  Specifically, 
if you do not have this capability, then you can't edit the pages of others.

It might not be exactly the solution, but I would be interested in 
seeing any alterations that allowed users with "edit_others_pages" to 
edit existing pages without allowing them to create new ones themselves.


Also, you can easily remove menus from the admin without buffering by 
hooking admin_menu, using $menu/$submenu as a global, checking for the 
conditions of display, then unset() the appropriate core menu item.

add_action('admin_menu', 'my_admin_menu');
function my_admin_menu() {
	global $submenu;
	if(!current_user_can('some_new_capability')) {
		unset($submenu['post.php'][10]);
	}
}


And finally, a rule of thumb:  NEVER check anything against a role name. 
  ALWAYS use a capability.  Why?  Capability names are not translated 
(__('Administrator') != 'Administrator'), and are not designed to be 
potentially deleted.
