And will the leaf respond on the fly and lower/raise current? I've been thinking about whether Open EVSE could be used to make a dual charger for a single 40A line and negotiate current between the two of them. Or possibly sharing a single 40A line with a garage heater (so when the heater is on, lower current to 14A or something).
The answers are Yes and Yes. You could definitely do this. There is a large installation in the LA area that does this with OpenEVSE based units. I tried to find a link for it, but couldn't.
