Why not use the .uid that mootools assigns as it deals with elements in
the DOM?
alert(document.getElementById("foo").uid); // undefined
var foo = $(document.body).getChildren(); // serialize - will assign
UIDS to returned elements and document.body.
alert(document.getElementById("foo").uid); // eg, 4

downside is, you redesign and put more nodes up the tree and the indexes
change, but you can use an anchor point of a parent, eg,
nav_inner.getChildren();
