To add, L2TP is only tunneling and not encrypted, which is why it is often used in combination with IPSec. It is used instead of pure IPSec because it allows non IP traffic, which in some cases is more important (e.g. windows non-IP netbios traffic interop when L2TP/IPSec was first made popular) and to confirm, yes, OpenVPN will run in IP or ethernet mode.
