Umm, simple. I do it all the time. (helps alot if u know somebody otherwise this will be a fail) but... gain a "physical address at least 4-6months in advance of your move. Have a company send you a bill or two there (or more) and get an I.D. Although CA is quite far away, it will be cheaper in the long run and you will technically cheat the system.

I did it when I was in GA, although I never actually lived there.
