HomePlug Green PHY

Has anyone done work on supporting this protocol? It could be good for both AC charging (get more info from the vehicle) and to explore DC charging too. I see there are a few modules around and I found this thesis from someone who (mostly) successfully added support for it to another EVSE:

I'm considering doing something similar for OpenEVSE... unless it has already been done?

I've investigated CCS / ISO15118 and yes, I know the protocol stack is a nightmare. Yes, there's nothing we can do about it; it's survivable. Also yes, I know the EVSE needs to control the DC charging voltage and current itself... some options are available.
