I had to do something similar, but used the jQuery treeview and added the checkboxes myself. Neither yours nor mine really deal with the check box hierarchy in a very intuitive way. When only some of the boxes under a node are checked, it seems like that node's checkbox does not behave right. In Windows you get the gray tristate checkbox for those situations. Clicking the checkbox in that state checks it and selects all descendants; clicking it again clears it and deselects all descendants. I didn't implement that but I did feel guilty about it. :-)
