Part of the reason business services were late getting DOCSIS 3 was because VPDN support, as in being a LAC, was either dodgy or non-existent in the early software.

Sorry, got my terminology the wrong way round (just like iSCSI, why can't they just call the blooming things "client" and "server")
Point still stands though: Superhub doesn't need a routable IP address for PPPoE but it does need one for L2TP. Superhub also has L2TP session entries in it's local log, which it would know nothing about if the CMTS was responsible for L2TP. Unless VM have sneakily shoehorned some proprietary remote L2TP tunnel state reporting mechanism into PPPoE...
