Of course. This example current uses a boost::shared_ptr, but it used to
just be a raw pointer:

	struct RegionListDisplayModelColumns : public
Gtk::TreeModel::ColumnRecord {
	    RegionListDisplayModelColumns() {
		    add (name);
		    add (region);
		    add (color_);
	    }
	    Gtk::TreeModelColumn<Glib::ustring> name;
	    Gtk::TreeModelColumn<boost::shared_ptr<ARDOUR::Region> > region;
	    Gtk::TreeModelColumn<Gdk::Color> color_;
	};
