JQuery nested sortable plugin

I've just come across this fantastic JQuery nested sortable plugin.

Initial testing of it shows it works well, and fingers crossed I'll be incorporating it into the CMS which we use for Vectis WebDesigns' clients.  My intention will be to use it as part of a menu creation system, allowing clients a simple way of re-ordering menu items, changing the sub-menu hierarchy, and then with the addition of some more JQuery, the ability to drag and drop new pages into the menu.
