I'm in Chicago, and here's what I know...
I've been looking into getting one too. GL is right about the training of the service guys. The service guys by me said that the training hasn't been brought to the local training facilities yet. They need a hybrid training car and they need a dude to conduct the training. So far, they've only had access to computer-based-training. If something happened to a non-hybrid part, you'd prob be able to get it serviced, but they still have to deal with working around the high voltage system, so even that could be problematic. Might be a good idea to talk to a local dealer and ask them "what if."
A part of me wonders if a Toyota dealer equipped to service the synergy drive would be able to handle it, since it's essentially the same (including the CVT, which apparently is different than the one in the standard alty)
As far as not being "allowed" to sell you a car, that's inconsistent with what the consumer affiars people are telling the public (although, to be fair, the CA people are also saying that it can be serviced at your local dealer too, so maybe they're smoking something completely magical).
I bet if you showed up with money and pointed to a car and said "you give me that, and I'll give you this," they'd sell you the car.
I wish Nissan would just go national with this thing already. Sigh.
