I would just render the item as inactive using cell renderer's "sensitive" property and prevent it from being selected using gtk_tree_selection_set_select_function(). You need to remember the current selection but otherwise it is pretty cheap: if the selected row changes only two rows have to receive "row-changed" to update the other treeview: the previously selected one (becomes selectable) and the newly selected one (becomes unselectable). Also, depending on the application this might be visually preferrable to appearing and disappearing rows.
