If I have the 4 paramNodes checked, I get 4 icons under each one instead of the specific one per layer (and it figures, because that's what it's configured to do).  You can see for yourself by replacing the mapPanel and tree in the tree-legend example with these [1].

The idea is to use the filter property of the loader (http://geoext.org/lib/GeoExt/widgets/tree/LayerLoader.html), and give your layers some information about the group they belong to (either in layer.metadata or in an additional field of a customized LayerStore) that you can filter against.
