Disclosure: I am not a Model S owner. In fact, I don't own a car yet (college). Still, it is my understanding that the forums can be used for discussion by non-owners.
In my just-created blog I've made what I believe is the most thorough analysis of ZEV credits yet. Okay, okay, there are more thorough things out there - but I've been unable to find them in web.
I know it sounds like the most spammish thing to do, linking to your own blog in the first post you make. Still, the point of this thread was to understand ZEV credits, so I think you'll see value in my article.

Summary:
-Four months after the event, there are no swap stations and no estimate on when the first one could be built, if at all.
-The production car cannot do what is shown in the video.
-Starting in 2018, ZEV credits will be awarded on range alone, so the loophole will be closed. This means 20% of the "loophole period" (2013-2017) for Tesla has already elapsed.
-CARB is aware of this and has extended the loophole for another year.
In the link you will find some other gems. For example, they did not actually use
the fastest gas station in LA.
