You'll have to incorporate into your tree item renderer whether your 'children' attribute is set to determine which field to show; you'll have to assign it 'by hand' or, if you know what the dataset is in the server side, just parse it such that you 'label' field gets built by back end logic to assign the appropriate field as the label. If you want them to be rendered differently, the icon classes are easily assign for branch v.leaf. if you want your display to be other, then your tree is not really so flat, as you'll either have to pass in which item should be a branch and which a leaf, or you'll have to dynamically figure it out within the item renderer itself.
Tree walking recursion functions really aren't that bad, computationally, if you are talking about ~<10000 or so (yes 10k). Try scaling for yourself once you've built a comfortable algorithm.
