Adding Site State To Menu

does anyone know where I would start with adding stats to the menu example:

Current menu look:

Want to add the future similar to this:

well the database tables   sys_stat_site and sys_stat_member...

Ads would be:

SELECT COUNT(`ID`) FROM `bx_ads_main` WHERE `Status`='active' AND UNIX_TIMESTAMP() - `bx_ads_main`.`LifeTime`*24*60*60 < `bx_ads_main`.`DateTime`

For the php i guess you could look in /templates/base/scripts/BxBaseMenu.php.

And you may need to edit navigation_menu.html or navigation_menu_item.html  ....  

I know there is more but that's start.  Be nice if you could trigger the sql statement in a language key.  not sure if that could be done or not.
