I think Craig McM is probably reading this thread and may be able to comment, but there's a member of the Ottawa EV group who has done a DIY automotive AC controller (not Craig, but he's probably got a better grasp on the technology than me).
He built an inexpensive AC Geo Metro conversion with regen, and has built an AC system for his riding lawn mower. He occasionally demonstrates the latest iterations of his controllers at the meetings.
I don't know enough about the technical details, and didn't pay a lot of attention to how he did it though.
