Instead of the node tool, you can use the "Reshape Features" <http://docs.qgis.org/testing/en/docs/user_manual/working_with_vector/editing_geometry_attributes.html#reshape-features> tool, which takes advantages of the auto tracing capabilities. It might behave like the "replace sketch" tool from ArcMap (for what i've understood from its description).
