My research turned up a few interesting things...

1) You can absolutely get J1772 chargers that will push 70A right now - and even better from a local company: http://evse.controlmod.com/
2) Turns out there is a DoE grant program offering free Coulomb chargers to new EV owners: http://chargepointamerica.com/search-zip-code.php

And the research continues - but hey, no car yet so... what's the rush? :-P
